Overview
JT14 is a pressure-sensitive floor mat for presence detection around machines and robot cells. Foot pressure changes its passive, volt-free normally open (N.O.) contact. A compatible safety mat controller evaluates the signal and works with the machine's stop interface; the mat does not stop a machine by itself. Its NBR rubber surface and aluminum trim edging suit rectangular or custom-shaped floor layouts.
Published JT14 series data lists an adult body-weight reference of ≥30 kg, a mat contact response of ≤30 ms, a compressive strength reference up to 1000 kg/cm², IP65 protection and a mechanical life of 1,000,000 operations. Mat response is not total machine stopping time, and the load reference does not establish forklift or wheeled-traffic suitability. Six catalog sizes from 250×500 mm to 1100×1800 mm and custom outlines are listed; confirm the exact active area and mechanical arrangement on the approved order drawing. Earlier series literature references ISO 13856-1 and PL d per EN ISO 13849-1; these references do not establish the achieved Performance Level or certification of a complete installation.
JT14 Applications & Control Connections
Four diagrams show how JT14 detects foot pressure, fits into a guarded-machine layout, connects to the control system and uses an active sensing area. The 750×750 mm outline is a custom-size example, not an additional standard catalog size.
1. How the Safety Mat Works
Foot pressure changes the mat contact. A matched controller evaluates the input and sends a protective stop demand through the machine's stop interface. The mat cable is a sensing connection, not a motor-power circuit.
- Detect: a person steps on the active sensing area.
- Evaluate: the compatible controller monitors the mat input.
- Stop: the machine's protective stop function responds; stopping time also depends on the controller, drive and mechanical run-down.
- Prevent restart: occupancy must inhibit hazardous restart. Stepping off the mat is not a Start command.
2. Application Example: A Guarded Rotating Machine
JT14 can provide a local floor-sensing position alongside fixed guards, a protected access gate and a safety control system. The five numbered parts below perform different jobs.
- 1 — Fixed guarding: separates people from the rotating hazard and restricts access around the sensing position.
- 2 — Rotating hazard: allow for inertia and run-down; a stop demand does not mean immediate standstill.
- 3 — Protected access gate: where a person could reach the hazard before it stops, suitable guard locking or another validated access-prevention measure is needed.
- 4 — JT14 safety mat: detects pressure at the selected position. Check gaps and bypass routes; more sensing coverage or guarding may be required.
- 5 — Safety control system: evaluates the mat, gate and emergency-stop functions and commands the machine's protective stop.
The complete layout must be assessed for the machine. A safety mat does not replace fixed guarding or maintenance isolation and lockout.
3. Control Connections
The mat connects to a compatible safety mat input. Gate protection and emergency stop are separate protective functions. The safety control system acts through the machine's final stop interface.
The N.O. mat contact is a sensing input, not a safety output. Use a controller matched to the delivered mat circuit, not an arbitrary relay input.
- Mat and cable: confirm the delivered cable pairing and circuit definition before wiring.
- Controller: match the input principle, fault detection and reset behavior to the mat circuit.
- Machine stop interface: use the specified safety drive or switching devices and required feedback monitoring.
- Reset and Start: place manual reset outside the hazard zone with a clear view. Reset must not start motion; provide a separate deliberate Start command.
Reset and Restart
Use the sequence protected area clear → specified manual reset → separate deliberate Start. Stepping off the mat, closing a gate or releasing an emergency stop must not automatically restart hazardous motion.
| Condition | System behavior |
|---|---|
| Mat occupied | Protective stop; hazardous restart inhibited. |
| Mat becomes clear | No automatic restart; confirm the whole protected area is clear. |
| Manual reset | Safety enable may be restored when all required conditions are satisfied; no hazardous motion starts. |
| Separate Start command | Operation may resume only with the safety enable and machine control conditions satisfied. |
4. Dimensions and Active Sensing Area
The 750×750 mm outline below is a custom-size example. Nominal size and active sensing area are different: aluminum trim and non-sensing borders must not be counted as protected floor coverage.
- Mounting: use a flat, clean, fully supported floor and the specified perimeter fixing method.
- Cable route: confirm the exit and lead length, then protect the cable from crushing, abrasion and trip hazards.
- Sensing core: do not cut, drill, fold or modify the mat.
- Coverage: check gaps, joints and routes around or over the mat; add sensing or guarding where required.
JT14 Sizes & Accessories
Choose a catalog size or ask about a custom outline to suit your machine layout.
- Sizes: six standard catalog sizes, with custom dimensions and polygon outlines available on request.
- Mechanical accessories: confirm the aluminum trim, fixing arrangement and cable length for your layout.
- Control: specify a safety mat controller compatible with the delivered mat circuit.
Installation & Routine Checks
Have a qualified integrator install and validate the complete safety function using the matched product and controller manuals.
- Before use: verify sensing coverage, complete stopping performance, fault response and safeguarding distance.
- Restart: verify occupancy prevents hazardous restart and that reset alone cannot start motion.
- Routine care: inspect the mat, trim and cable. Stop use if damage or unreliable detection is found.
Features & Benefits
Actuating force ≥ 30 kg
Published adult body-weight reference. Verify detection over the delivered active area and actual conditions; it is not a precise universal force threshold or a guarantee against nuisance trips.
Response time ≤ 30 ms
Fast signal output from actuation to contact switching. Total machine stopping time still depends on the connected equipment's braking performance, not the mat alone.
Load rating up to 1000 kg/cm²
Published series compressive-strength reference. Confirm the applicable test and permitted loading; do not infer suitability for forklifts, pallet trucks or other wheeled traffic.
IP65-rated sealed construction
Dust-tight and protected against water jets, suitable for floor areas that require washdown cleaning.
NBR rubber surface with aluminum trim edging; 1,000,000-operation mechanical life
The trim edging protects the perimeter of the sensing core — the most vulnerable point — and reduces trip hazard from a raw edge, while the rated mechanical life supports long-term repeated use.
Passive volt-free N.O. contact output
No independent power supply is required at the mat itself. Use a matched safety mat controller; the complete system must provide the required diagnostics and fault response.
ISO 13856-1 / PL d references in series literature
Request documents for the exact delivered configuration and verify their scope. A catalog reference is not proof of third-party certification or the achieved Performance Level of an installed safety function.
Custom sizes and free polygon shapes
Beyond the 6 catalog sizes, request custom dimensions and polygon outlines to follow the machine footprint. Confirm feasibility, active-area boundaries and all potential gaps on the approved layout.
Economical positioning for large-area or multi-zone guarding
Catalog-designated economical tier, offering a cost advantage when guarding large continuous areas or multiple work zones.

How to Select
- Choose from the 6 standard sizes (250×500 mm to 1100×1800 mm) named as JT14-Width*Length (mm).
- All 6 standard sizes are rectangular; for irregular boundaries such as machine bases, columns, or cable runs, request a custom free-polygon layout with your site outline dimensions.
- The mat outputs a passive volt-free N.O. contact. Specify a controller demonstrably suitable for the delivered mat circuit; confirm the complete model combination, input principle, diagnostics, cable pairing and matched terminal diagram before ordering.
- For washdown or wet floor areas the IP65 rating applies; confirm chemical or oil resistance separately if your environment requires it.
- If the risk assessment specifies a required Performance Level or pressure-sensitive protective-device requirements, request applicable documentation and verify its exact scope. The complete safety function still requires machine-specific design and validation.
When NOT to specify the JT14 — and what to use instead
Guarding a perimeter or vertical opening rather than a floor area
Why not: JT14 is a floor presence mat that detects step-on pressure; it does not sense intrusion into a vertical plane.
Use instead: A light curtain (DQC/DQA/DQT/DQT4) or ST27 laser scanner for perimeter/area guarding
Forklifts, pallet trucks, or other wheeled loads will drive over the guarded area regularly
Why not: JT14's compressive strength rating is up to 1000 kg/cm²; sustained wheeled-vehicle traffic beyond typical foot-traffic duty is not confirmed as within its rated use.
Use instead: Confirm loading with the factory; a hard guard fence or a light curtain may better suit vehicle-trafficked boundaries
Needing a self-contained safety function without an external compatible controller
Why not: JT14 is a passive sensing element, not a complete safety system. Input evaluation, required diagnostics and the validated machine stop interface must be provided externally.
Use instead: Specify a demonstrably compatible safety mat controller and validate the complete machine safety function; no DA31/DQSRN compatibility is assumed here.
Detecting a body weight lighter than an adult (e.g. a light object or small load) must reliably trip the mat
Why not: Actuating force is rated at '≥30 kg for an adult' — loads lighter than this are not guaranteed to trigger the contact.
Use instead: Consult the factory for lower-threshold sensing needs
The environment involves oil or specific cleaning chemicals beyond plain water washdown
Why not: IP65 protects against dust and water jets but 'does not by itself indicate resistance to specific cleaning chemicals or oils' per the product's own FAQ.
Use instead: Confirm chemical/oil resistance with the factory before specifying
