The OMRON/STI TL5012-2024SM is a compact safety interlock switch engineered for machinery safeguarding and guard-door locking applications. Operating on a power-to-unlock principle, the switch maintains a locked guard door until the machine reaches a safe state. The solenoid energizes to release the locking mechanism, providing positive opening action with a safety contact gap exceeding 2 mm. Built for harsh industrial environments including water washdown operations, this unit delivers a maximum holding force of 1000 N and mechanical life rated to 1,000,000 actuations.
