RUKO MGB-FormB-HSS-PG-29 Modular Guard Locking System, PROFINET/PROFIsafe, Spring Force Locking, IP65/IP67, PG29

The RUKO MGB-FormB-HSS-PG-29 is a modular guard locking system from the MGB-B series, offering robust safety interlocking for machine guarding applications. Its standout capability is guard locking by spring force with release by solenoid, ensuring the guard remains securely locked until safe conditions are met, even in the event of power loss.

Advantages

This device provides high-level safety with Performance Level e (PLe) and Category 4 according to ISO 13849-1. It features two p-switching safety outputs (OSSD) and two auxiliary outputs, plus a diagnostic output for comprehensive status monitoring. The high coding level actuator (per ISO 14119) minimizes the risk of tampering or bypassing. With an IP65/IP67 protection class, it withstands harsh industrial environments. The housing is made of glass-fibre reinforced thermoplastic, self-extinguishing, ensuring durability. A manual release function allows opening the guard in emergency or maintenance situations.
