Fermax Lock Release 540N-512-M Max

Fermax 64802 Electric Lock Release 540N-512-M Max (12Vdc Fail Secure, Low Current, Monitored)

The Fermax 64802 is an advanced electric lock release designed for 12V DC systems, offering fail-secure operation, low current consumption, an adjustable latch, and integrated monitoring contacts. The designation details: 540 series standard body, N operation (Normal Fail Secure), 512 voltage (12V DC Low Current), M type monitored shield, and MAX adjustable latch.

Key attributes include: 540 standard body. N fail-secure operation (locked without power, unlocks with continuous 12V DC). 512 low current 12V DC draw, suitable for power-sensitive systems. MAX adjustable jaw (±4mm) for optimal alignment. The crucial M indicates this version includes integrated microswitch monitoring contacts (typically Normally Open/Normally Closed/Common). These contacts change state depending on whether the strike jaw is closed (door shut and latched) or open, providing feedback to the access control or security system about the doors status (latched/unlatched). The M shield is usually the standard size (approx 25x160mm) but accommodates the monitoring switch.

This model is ideal for higher security applications or where door status monitoring is required (e.g., integration with alarm systems, timed access control). It combines reliable fail-secure locking, low power usage, installation flexibility via the MAX latch, and the valuable feedback from the monitoring contacts, all operating on 12V DC.
