Typical Wiring Use

The NXB52AZ1SMK is typically integrated into safety circuits where the dual safe outputs (OS1, OS2), dedicated signal outputs, and feedback circuits are monitored by safety relays or PLC safety modules. The 12-pin M12 connector streamlines the electrical interface for rapid setup and reliable system integration. Always refer to the official wiring diagram and validate the required safety function in accordance with your risk assessment and compliance obligations.

Maintenance and Inspection

Routine inspection should confirm proper mechanical and electrical operation, integrity of connection points, and correct functioning of all safe and signal outputs. Damaged, worn or contaminated devices must be replaced in line with manufacturer recommendations and as part of machine safety validation protocols.

Safety note: Guard locking safety switches are part of safety functions. Selection and integration must be verified against your machine risk assessment and compliance requirements. Always follow installation and wiring guidelines provided by the manufacturer.
