With its dual entry slots and rotatable head,the MT-GD2 can offer eight different options for actuator MT-GD2 features a compact housing of only 117 x 40 x 43 mm( x x in.)

5 With DIN 50041 standard fixing centres andincludes forced guided contacts and a tamper-resistant MT-GD2 is available with a variety of contact configurationsenabling it to be used as part of a system for higher-riskapplications. Operation of the switch is achieved by the insertion ofthe specially-profiled stainless-steel actuator which should bepermanently fixed to the leading edge of the guard door. An optionalflexible actuator allows the MT-GD2 to operate on smaller-radiidoors ( 60 mm) and a flat actuator gives additional mountingoptions, for example, on a style incorporating a latch release mechanism allows manualretention of the actuator in the switch until the release mechanism ismanually :03-SafetySw1 5/6/2010 10:53 AM Page 3-28 AUDIN - 8, avenue de la malle - 51370 Saint Brice Courcelles - Tel : - Fax : - Web : http: - Email : SwitchesTongue Switches3-29MT-GD2 Visit our website.
