The actuator is too far from the sensor or is the wrong model. Ensure you are using the GS-A22 or GS-A30 actuator. keyence gs-11pc manual
The Keyence GS-11PC is a non-contact safety interlock switch designed for industrial automation environments. This electromagnetic safety sensor is part of the GS Series, known for its robust reliability, slim profile, and ease of installation.
The GS-11PC model is a PNP output type sensor that utilizes a dedicated actuator to monitor the status of doors, gates, and safety guards. Warning state (near the limit of the sensing range)
Proper wiring is essential to ensure the safety circuit functions as intended. The GS-11PC uses a standard 8-pin M12 connector. 1. Wiring Pinout (PNP) +24 VDC. Blue: 0 V. White: OSSD 1 (Safety Output). Black: OSSD 2 (Safety Output). Grey: AUX Output (Non-safety, used for PLC monitoring). Pink: Reset/EDM Input. 2. Mounting the Actuator
Industrial safety standards (ISO 13849-1) require periodic testing of interlock devices. The Keyence GS-11PC is a non-contact safety interlock
Whether you are an automation engineer or a maintenance technician, understanding the technical specifications and installation procedures found in the manual is critical for maintaining a safe and compliant workspace. Core Features of the GS-11PC
Its compact footprint allows for mounting in tight spaces where traditional mechanical interlocks cannot fit.
Check for physical damage to the sensor housing or the M12 cable.
