Seco-Larm - E-941SA-600PD - 600-lb Electromagnetic Lock, Bond Sensor, Status LED, Timer, UL Listed
Product Overview
The E-941Sx series electromagnetic lock is designed to secure doors against unauthorized entry using a strong magnetic holding force. When powered, the lock attracts the steel armature plate mounted on the door, and when deactivated, the door operates normally without residual magnetism.
Key Configuration
Electromagnetic door lock with 600 lb. / 272 kg holding force; selectable 12/24VDC operation; built-in bond sensor with 1A at 30VDC dry relay output for monitoring door status.
Key Features
• Provides 600 lb. / 272 kg holding force for secure door locking
• Built-in status LED shows locked or unlocked status
• Built-in timer is adjustable from 1 to 78 seconds
• MOV surge protection helps protect against voltage spikes
• Detachable faceplate and adjustable mounting bracket support easier installation
Technical Context
The lock uses electromagnetic force to hold the door closed while power is applied and releases when power is removed. The built-in bond sensor provides monitoring feedback through a dry relay output, allowing compatible access control systems to detect lock or door status.
Installation Notes
Complete mounting hardware is included for typical installations. Optional “L” and “Z” brackets are available to simplify mounting in different door and frame configurations.
