G9SX-SM Standstill Monitoring Safety Unit G9SX-SM032-RT
OMRON — G9SX-SM Series (G9SX Flexible Safety Units)
The G9SX-SM032-RT is a safety unit from OMRON's G9SX flexible safety unit family that detects standstill (zero-speed) directly from the motor's back-EMF signal, without requiring an external sensor. Once the motor has fully stopped, it provides a safe output that allows functions such as guard-lock release or safe operator access to the hazard zone to activate. It is DIN-rail mounted and provides a high performance level per ISO 13849-1.
Key Features
- Direct standstill/zero-speed detection from motor back-EMF signal, no external sensor required
- ISO 13849-1 high performance level (PL e) safety outputs
- Compact DIN-rail mounted housing
- LED status indicators and fault diagnostics
- Suited to integration with guard-lock release or safe-access permission functions
- Part of the G9SX flexible safety unit family
