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.
