Sentrol 2757D High Security Contact






High Security Contacts, Triple Biased, DPDT, Ansi Recessed, 0" To 3/8" Gap Size. Double Pole-Double Throw

Special Order


Specifically designed for high-security applications in prisons, military installations, government facilities, and commercial operations, the 2757/2767 series magnetic contacts are virtually impossible to defeat. Total encapsulation coupled with recess mounting prevents access to the switch and to cabling, and prevents tampering with an external magnet.

The contacts are factory-calibrated for operation in steel and are not subject to sticking or freezing on seldom-used doors.

The 2767 model is adjustable for versatile alignment.
