Emergency Stop Switch
A165E
Mounting Aperture of 16 mm
* Modular construction, easy installation * Direct opening mechanism with minimum contact separation of 3 mm in accordance with EN60947-51, AE . (only for NC contacts) * Conforms to EN418, EN60947-5-1. * Includes a safety lock to prevent misuse. * Features separate construction that allows the Switch to be separated for easier wiring and onepiece-like construction that allows easier handling. * High reliability, IP65 * Short mounting depth, less than 28.5 mm below panel * Quick and easy assembly, snap-in Switch. * A165E is identifiable, clearly visible and will stop a dangerous process, without creating additional hazards.
