Product Description

The Keyence GS-5PNP is a non-contact safety interlock switch designed to enhance machine safety by preventing unauthorized access to hazardous areas. Utilizing a power-to-lock mechanism, it ensures that doors remain securely closed during machine operation. The GS-5PNP features a robust locking force of at least 2,000 N and is engineered for high durability with a mechanical lifespan exceeding 1 million cycles. It supports cascading up to 25 units, facilitating flexible system configurations. The switch complies with international safety standards, including EN 61508 (SIL2/SIL3) and EN ISO 13849-1 (PLd, Category 2/PLe, Category 4), ensuring reliable performance in demanding industrial environments.​
