LOB RE41AADF Automatic Electromagnetic Strike 12V Fail-Secure Memory Switch 3000N

Product Overview

The RE41AADF LOB is an automatic electromagnetic strike with memory and an integrated switch, tailored for use in professional access control systems for commercial, institutional, and residential applications. Its fail-secure design ensures the strike remains locked upon power loss, and the device operates at 12V AC/DC. Ruggedized for security installations, it is verified for 20,000 work cycles and supports a holding force of up to 3000 N, making it suitable for entrances subject to moderate security requirements and moderate usage.

This model's primary differentiator is its combination of memory function and switch, which enhances access control versatility by allowing users to retain unlock status until the door is opened, and offers manual override capability. This addresses project requirements where both secure fail-safe operation and on-demand release flexibility are necessary. The RE41AADF is particularly well-suited for building contractors, integrators, and OEMs specifying door entry systems for office complexes, multi-tenant buildings, and premium residential developments.
