Procurement Notes

Verify that the specific订货代号 matches the required resolution and height configuration for your safety circuit design. Ensure compatibility with the intended controller or safety relay regarding the switching output type and wiring scheme. Confirm that the environmental conditions align with the IP67 rating and operating temperature specifications before finalizing the order.

Selection Notes

Select this model based on the required 40 mm resolution for finger protection and the 900 mm height to cover the specific hazard zone. Consider the mounting orientation and available space for the emitter and receiver units. Evaluate the need for additional accessories such as reflectors or mounting brackets if direct line-of-sight installation is not feasible.

Part Context

This component is part of the M4000 series safety light curtains, which are engineered for demanding industrial safety applications. The series offers various resolutions and heights to meet different risk assessment requirements. It integrates seamlessly with SICK's broader safety ecosystem, allowing for straightforward integration into existing machine control architectures.

Replacement Considerations

When replacing older models, verify that the new unit's electrical connections and mounting dimensions are compatible with the existing setup. Check if the previous model utilized a different resolution or height that might necessitate adjustments to the safety distance calculations according to relevant standards.
