JANTEK JEB-220 Electromagnetic Bolt Lock 12V DC Adjustable Locking Delay

Product Overview

The JANTEK JEB-220 electromagnetic bolt lock is a fail-safe (NO) type lock designed for access control systems in commercial and institutional environments. Operating at 12V DC, it supports both vertical and horizontal mounting orientations, offering flexibility for installation in various door frames and gates. Power-up closes the lock, and it features current draw values of 700 mA at startup and 200 mA during operation.

Adjustable locking delay?from 0 to 9 seconds?distinguishes this model from generic electromagnetic bolts, allowing installers to configure door closing times tailored to security or access control needs. This feature helps eliminate access timing disputes in high-traffic facilities, making the JEB-220 well-suited for B2B buyers managing security systems in commercial offices, multi-tenant buildings, or institutional access control upgrades.
