RUKO MGB-FormB-HSS-PG-21 Safety Guard Locking Device

The RUKO MGB-FormB-HSS-PG-21 is a modular safety guard locking device from the MGB-B-H series. It features a power-to-unlock principle, meaning the guard is locked when the solenoid is de-energized. This design ensures the guard remains locked in the event of a power failure, enhancing safety in industrial applications.

Highlights

• High locking force of 2500 N
• Safety classification PLe / Category 4 (ISO 13849-1) and SIL 3 (IEC 61508)
• Integrated handle module with high coding level (unique coding)
• Robust glass-fibre reinforced thermoplastic enclosure, IP65 rated
• Operating temperature range from -25 °C to +60 °C

In daily use

This device is suitable for safeguarding movable guards such as doors, flaps, or hoods on machinery. The integrated handle module allows for ergonomic operation, while the high coding level prevents tampering. The device provides multiple safety and auxiliary contacts for guard locking and door position monitoring, enabling flexible integration into safety circuits.
