Overview
JB is an economy-line pressure-sensitive safety edge — a flexible rubber profile that trips a switching signal when compressed by contact. It protects the closing edge of doors, gates, and moving machine components from pinching or crushing a person or object, and is intended for general anti-pinch applications where a control unit or PLC already handles the safety logic.
The series offers 37 rubber cross-section profiles from 5 mm to 90 mm high and 6 mm to 65 mm wide, so it covers most door and machine edge geometries. Catalog-listed profiles switch at an actuating force of 30 N or less with a 2-8 mm actuating travel, and up to 5 edges can be daisy-chained to a single controller input, wired directly to a PLC e-stop input or, for normally-closed logic, through an interposing relay.
Features & Benefits
37 Cross-Section Profiles, 5-90 mm High
Covers virtually any door or machine edge geometry without redesigning the mechanical structure. Useful as a form-fit replacement for an existing worn safety edge.
Economy Line for General Anti-Pinch Protection
Pay for the protection you need in non-certification-mandatory scenarios, without the added cost of functional-safety performance data.
Low, Uniform Actuating Force
Catalog-listed profiles (32 of the 37) trigger at an actuating force of 30 N or less with an actuating travel of 2-8 mm, giving a consistent, gentle trip response.
Daisy-Chain Up to 5 Edges per Controller Input
Protect the full perimeter of a door frame or platform with a single circuit, reducing wiring and PLC I/O point cost.
2-Wire Monitored Version with 8.2 kΩ Terminating Resistor
An integrated 8.2 kΩ / 0.25 W terminating resistor lets the control unit continuously supervise the circuit for wire breakage and short circuits.
Direct-to-PLC Wiring Diagrams Provided
Wiring diagrams cover direct connection to a PLC e-stop input (normally open), or normally-closed operation via an interposing relay, so the edge integrates without a proprietary controller.
Custom Length, 20 cm to 300 cm
Order to fit your door width or edge length without on-site cutting or splicing, in standard (R) or special-shape (S) versions.
IP65-Rated EPDM Rubber, -20 °C to +80 °C
Suited to indoor and outdoor installation across a wide range of industrial conditions.
Conformable Mounting for Curved Edges
Profiles can be mounted along curved or irregular edges, and a minimum bending radius (from ≥55 mm) is published for most, though not all, of the 37 profiles.
Near Full-Length Sensing Coverage
Insensitive end zones of only 20-30 mm per side keep the effective sensing length close to the full length of the edge.
Applications
Models & Ordering Information
Cross-Section Profiles (JB-1 to JB-37)
How to Select
- Select the cross-section profile (JB-1 to JB-37) by measuring the groove or edge dimensions to be protected — heights range from 5 mm to 90 mm and widths from 6 mm to 65 mm.
- Check the actuating force and actuating travel against the catalog parameter table, which covers 32 of the 37 profiles (actuating force ≤ 30 N, actuating travel 2-8 mm); confirm the remaining 5 profiles (JB-02, JB-04, JB-13, JB-18, JB-26) directly with the manufacturer.
- For curved or arc-shaped installation, prefer profiles with published minimum bending radius data (from ≥ 55 mm, varies by profile); profiles without published bending radius data should be confirmed with the manufacturer before curved installation.
- Choose the wiring configuration based on monitoring needs: select the 2-wire version with 8.2 kΩ terminating resistor (R) for wire-break/short-circuit supervision, or the 2/4-wire version without a resistor (K) if monitoring is not required.
- Match the signal logic to your control system: connect directly to a normally-open (N.O.) PLC e-stop input, or use an interposing relay for normally-closed (N.C.) logic.
- Specify the overall length to fit your door width or edge length, from 20 cm to 300 cm, in standard (R) or special-shape (S) form.
- Confirm the control circuit matches the signal loop rating: ≤ 24 V, < 1 A, with a standard 50 cm cable (customizable length).
When NOT to specify the JB — and what to use instead
A formal machine risk assessment requires documented PFH/Category/PL/SIL performance data for the safety edge itself
Why not: The JB series' own FAQ states it 'does not include published functional-safety performance data, over-travel specification, or response-time figures' in the current catalog.
Use instead: JB-PSE series, which carries published PFH, Category 3, MTTFd, and B10d data
Needing to detect presence at a distance rather than by direct contact
Why not: JB is a pressure-sensitive contact edge triggered by direct compression (2-8 mm actuating travel on catalog-listed profiles), not a non-contact presence sensor.
Use instead: A light curtain (DQC/DQA/DQT/DQT4) or ST27 laser scanner
Guarding a floor area instead of a single moving edge
Why not: JB is a linear edge profile (20-300 cm made to order); it is not a floor-coverage device.
Use instead: JT14 safety mat
The specific profile needed is one of the five without published actuating-force/travel data (JB-02, JB-04, JB-13, JB-18, JB-26)
Why not: The catalog parameter table covers only 32 of the 37 profiles for actuating force and travel; these five are not published.
Use instead: Confirm these five profiles directly with the factory, or select from the other 32 documented profiles
Curved or arc-shaped installation is needed on a profile without a published minimum bending radius (JB-06, JB-16, JB-24, and JB-28 through JB-34)
Why not: Minimum bending radius data is not published for these specific profiles in the current catalog.
Use instead: Confirm with the factory before curved installation, or select a profile with published bending-radius data
Specifications we do not publish yet
We only publish a figure once we are confident it is true. The items below are still being validated through further testing and real-world customer feedback, so for now we would rather leave them open than guess. If one of them matters to your design, ask us for the latest validated status.
- Response time (not specified anywhere in the available catalog data for the JB series)
- Actuating force/travel for JB-02, JB-04, JB-13, JB-18, and JB-26 (5 of the 37 profiles)
- Minimum bending radius for JB-06, JB-16, JB-24, and JB-28 through JB-34
- Formal SKU numbering format — the catalog shows both single-digit (JB-1) and zero-padded (JB-01) styles across source pages
- PFH, MTTFd, B10d, Category, PL, and SIL figures (none published for this economy line)
- Certificate numbers and issuing body for any compliance claim
