Procurement Notes

Verify the specific model suffix against the official SICK datasheet to ensure compatibility with existing transmitter units and control systems. Confirm that the required resolution and height match the safety risk assessment. Check for any regional certification requirements such as CE or UL marking before procurement.

Selection Notes

Select this receiver based on the required beam spacing and vertical detection height determined by the machine's hazard analysis. Ensure the operating voltage and output type match the safety PLC or relay inputs. Consider environmental factors like ambient light interference when choosing between different series options.

Part Context

This component belongs to the SICK C4000 safety light curtain family, known for its compact design and high performance. It is part of a modular system where transmitters and receivers are paired to create protective fields. The C4000 series is widely used in automation for personnel protection.

Replacement Considerations

Direct replacement requires matching the beam pitch and active height. Verify electrical pinout compatibility with the existing controller. Consult SICK documentation for cross-reference lists if upgrading from older series like C40E.
