## What we do

- Manufacture and supply the sensor and machine-safety product lines listed above, factory-direct from Foshan, Guangdong, China.
- OEM / ODM: custom housings, cable lengths, connectors, labelling and model codes on our existing platforms.
- Supply the operating instructions, wiring information and technical data needed to design our products into a machine.
- Send certification documentation on request, for the exact model code you intend to use.

## Capability boundaries — what we do NOT do

- We do not provide machine risk assessments, safety-distance calculations or CE marking for your machine. Those are the machine builder's or integrator's responsibility under ISO 12100 / ISO 13849-1 / ISO 13855. We publish the device parameters those calculations need (response time, extension distance ZR, tolerance zone, object resolution) and worked examples that illustrate the formulae only.
- We do not claim third-party certification we cannot document. Where a certificate exists we send it on request; where a figure is not published in the product's operating instructions we say so rather than estimate it.
- We do not publish PFHd, MTTFd or TM figures for every product. Where they are not in the manual, ask and we will confirm with the factory before you design the product in.
- Our LiDAR products fall into two distinct groups and they are not interchangeable: the ST27 series is safety-rated electro-sensitive protective equipment (Type 3 / SIL 2 / PL d, OSSD outputs); the DLD and SDLD series are obstacle-avoidance and measuring LiDAR with no safety rating and ordinary discrete outputs, and must never be used as the protective device in a machine safety function.
- Safety laser scanners resolve 70 mm objects and suit leg, body and vehicle detection. They do not protect fingers (14 mm) or hands (30 mm) — that needs a safety light curtain.
- We are a manufacturer, not a systems integrator. We do not install, commission or validate safeguarding on site.
