Overview
The Sentrol 109-6N is a Level 1 non-contact safety interlock position switch from the GuardSwitch Series. Manufactured by Edwards Signaling, this device detects the position of guards, gates, and movable safety devices without requiring direct mechanical contact. The non-contact design eliminates wear and provides consistent, reliable operation in harsh industrial environments where moisture, dust, and temperature extremes are common.
