描述

The A02ESH3B112IX0 is a high-security emergency stop switch from the A02ES-H series designed with failsafe modular construction to ensure the highest security level. It features double pole normally closed contacts combined with single pole normally open contacts, with electrical ratings of AC-12 3A 250VAC and DC-12 2A 30V for NC contacts, and AC-12 0.6A 250VAC and DC-12 2A 30V for NO contacts. The switch operates with a push-to-shut-off function and pull-or-twist-to-release mechanism, with an operating force of 32N for push and 21N for pull, and is approved to EN 60947-5-5 and UL 508 standards. The panel-sealed design achieves IP65 front panel sealing with IP20 terminal protection, operates across -25°C to +60°C, and supports a mechanical life of 250,000 cycles with 100,000 electrical cycles. This failsafe design ensures that if the operator or switch block becomes separated, the circuit will open, making it ideal for critical safety applications in industrial machinery and emergency shutdown systems.
