Stainless steel access interlocks designs for hygienic areas

Paul Boughton
Fortress Interlocks is adding the DMSK to its DM (door module) robust modular range of access interlocks. The DMSK is a stainless steel single-door interlock that is designed for hygienic areas and is suitable for all types of door. Its minimal design helps to reduce dirt traps while protecting workers from hazardous areas.
As part of an interlock system, DM locks are used to control access to enclosed areas until a safe condition has been achieved. In a typical operation sequence, the key is inserted into the lock and turned; doing so disengages the actuator so that the door may be opened. The key remains trapped until the door is closed and the actuator re-engaged (other sequences are available).
According to Fortress Interlocks, the DM module benefits from a revolutionary head design that features a choice of four head rotation angles with an adjustment of 360 degrees at 90-degree increments and two actuator entry points.
The head, all internal contact components, actuators and key are constructed using stainless steel. Tested to over 1,000,000 operations, the units have tamper-resistant head mechanisms and require minimal maintenance.
