With its dual entry slots and rotatable head, the MT-GD2 can offer eight different options for actuator entry. The MT-GD2 features a compact housing of only 117mm x 40mm x 43mm with DIN 50041 standard fixing centres and includes forced guided contacts and a tamper-resistant mechanism. The MT-GD2 is available with a variety of contact configurations enabling it to be used as part of a system for higher-risk applications. The unit is sealed to IP67 and has 1 conduit entry. Operation of the switch is achieved by the insertion of the specially profiled stainless steel actuator which should be permanently fixed to the leading edge of the guard door. An optional flexible actuator allows the MT-GD2 to operate on smaller radii doors (≥60mm) and a flat actuator gives additional mounting options. A style incorporating a latch release mechanism allows manual retention of the actuator in the switch until the release mechanism is manually activated. 500V 240V 120V 1.4A 3A 6A 500V 250V 125V 0.55A 1.1A 2.2A Rtd.

IMPORTANT: It must not be possible to lift the guard without actuating the interlock. An interlock on either side may be required. 3-22 Interlock Switches Tongue Switches MT-GD2 Approximate Dimensions—mm (inches) Dimensions are not intended to be used for installation purposes.
