A165E
Emergency Stop Switch
A165E
Mounting Aperture of
16 mm
• Modular construction, easy installation
• Direct opening mechanism with mini-
mum contact separation of 3 mm in ac-
cordance with EN60947-5-1, . (only
for NC contacts)
• Conforms to EN418, EN60947-5-1.
• Includes a safety lock to prevent mis-
use.
• Features separate construction that al-
lows the Switch to be separated for
easier wiring and one-piece-like con-
struction that allows easier handling.
