Omron · Mechanical & Power Transmission

Description  The G9SX‑SM032‑RC is a DIN‑rail mount standstill monitoring (shaft control) unit from Omron’s G9SX series. It uses a sensorless method to detect motor standstill by monitoring back-EMF, offering up to Safety Category 4 / PL e protection.     Technical Specifications  Condition New/Never Used Surplus Brand Omron  Category Panel Accessories Part Number G9SX-SM032-RC Subcategory Relay/Socket Function Sensor-less monitoring of machine standstill Application Safety standstill detection for rotating machinery Safety Outputs 3 PNP outputs Auxiliary Outputs 2 PNP outputs Rated Voltage 24 V DC Inertia Handling Suitable for systems with long inertia Terminal Type Spring-cage terminals Weight 1.00 lbs       Information About G9SX-SM032-RC The G9SX-SM032-RC is a compact, sensorless standstill monitoring unit from Omron’s G9SX safety series, designed to ensure safe machine access by detecting the complete stop of rotating machinery. Using back-EMF detection, it eliminates the need for external sensors, offering a space-efficient and cost-effective solution for motor stop verification in safety-critical environments. Built to meet PL e / Category 4 / SIL 3 safety standards, the unit is ideal for guarding, interlocking, and safety shutdowns in high-inertia applications. Key Features: Sensorless Standstill Detection: Uses motor back-EMF signals to determine when the shaft has stopped, requiring no physical sensors or encoders. High Safety Certification: Meets stringent safety requirements—EN ISO 13849-1 PL e, IEC 61508 SIL 3, and EN 62061 SILCL 3—for reliable operation in safety systems. Multiple Safety Outputs: Equipped with three PNP safety outputs (300 mA max each) and two auxiliary outputs (100 mA max each) for flexible system integration and diagnostics. Rapid Response Time: Standstill detection triggers within ≤ 50 ms, ensuring prompt disconnection of hazardous energy. Dual-Channel Monitoring: Accepts two separate motor phase pairs (Z1–Z2 and Z3–Z4), enabling redundant or multi-motor monitoring configurations. 24 VDC Operation: Designed to run on standard 24 VDC power supplies used in safety and control panels. Robust and Compact Design: DIN-rail mountable module with spring-cage terminals for quick and secure wiring; rated for environments from –10 °C to +55 °C. Ideal for Long Inertia Loads: Suited for machines where coast-down time is significant and precise confirmation of standstill is critical. The G9SX-SM032-RC remains a reliable and efficient solution for sensorless standstill detection in industrial safety systems. Its compact design, compliance with top-tier safety standards, and simplified wiring make it a smart choice for retrofitting or building safe access systems around high-inertia rotating equipment.
