Electronic lock systems for office furniture

German furniture lock specialists Lehmann offer the „M300“ and „M400“ electronic lock options to provide a complete range of remote-control operated systems that can be fitted to almost any office furniture application. With „M300“, the focus is on high motor power, making it possible to move bar mechanisms for lateral file cabinets or tall door cabinets. As a simplified version, „M400“ is for locking of smaller doors or drawers.

Both the „M300“ and „M400“ systems work on standard batteries. „M300“ can be used for transferring forces in 3 directions, which means that bars or bolts can be moved to lock, for example, a double door cabinet. It is possible to connect an optical unit with red and green light-emitting diodes.

With the “M400”, the motor, lock and electronics are accommodated in one unit. The „M400“ lightweight version provides convenient security wherever lower strength requirements are involved. Both versions can be used for locking and unlocking cabinet elements separately.

With remote-control operated solutions for complete office furniture ranges, the office user can lock and unlock his personal cabinets at the press of a button.
