The OMRON/STI TL5012-1024SM is a compact safety interlock switch that prevents access to hazardous machinery when guards or doors are open. Operating on a power-to-unlock principle, the switch maintains guard door locking via solenoid control until a signal is applied for unlocking. The tongue-operated design delivers a maximum holding force of 1000 N (225 lb), securing the guard door until the machine reaches a safe state. Its 180° rotatable head provides four possible actuator entry points, enabling flexible installation in confined spaces. The switch requires minimum 2.45 mm actuation distance between switch face and actuator face to engage the locking mechanism. Emergency override capability uses a Torx screwdriver or optional override key for manual release. A lid-mounted status indicator illuminates when the solenoid is energized, confirming guard door unlock status.
