SECO-LARM ELECTROMAGNETIC LOCK

Table of Contents:
Introduction:

Features:

The E-941SA-300RQ electromagnetic lock is the ideal way to secure a door against unauthorized
entry. When power is applied to the electromagnetic lock, it creates an extremely strong magnetic
field. The electromagnet is strongly attracted to the steel armature plate which is mounted on the
secured door. Once the electromagnet is deactivated, the secured door will function normally without
any residual magnetism.

 Anodized aluminum.
 No residual magnetism.
 MOV surge protection.
 Magnet can be reversed for use with right-swing or

left-swing doors (default left-swing).

 Adjustable mounting bracket.
 Complete mounting hardware for typical installations.
 “L” brackets, “Z” brackets and “U” brackets are

available for easy mounting.

 Selectable 12/24 VDC.
 Detachable faceplate.
