High-Security Emergency Stop.

The APEM AO2ES-H Series is an emergency stop switch with exclusive “built-in-safety” design. Certified to the highest safety standards: UL 508, CSA 22.2, EN 60947-5-5 and EN 60547-5-1. For dia. 22 mm panel cut-out. Easy to mount and operate. The illuminated version available. The APEM A02ES-H series has been designed to ensure the highest security level. By design, this product has a failsafe modular construction.
Many other emergency stop switches are not failsafe and rely on butt action contacts: the NC contacts remain closed until the actuator is pressed. Therefore, if the switch is damaged, destroyed or assembled incorrectly, the contacts remain closed. On the A02ES-H, if the operator or switch block become separated, the circuit will open.

Main features include:

  • High security: no risk of accident in the assembly and maintenance phases
  • Push to lock, pull or twist to release
  • Current/voltage rating: AC-12, 3A 250VAC / DC-12, 2A 30VDC
  • Panel sealed to IP65
  • Mechanical life: 250,000 cycles
