Sealed components resist water, dirt and are more accommodating to misalignment than mechanical switchesCompact size makes it possible to conceal the switch three housing styles are available for flat or 30 mm barrel-style mounting models to provide one normally open (NO) and one normally closed (NC) actuator contact shifts in distance and alignment don’t compromise sensing coded magnets minimize the risk of intentional defeat agents with different polarizations add security for safety applications, the switch must be used with gate monitoring module GM-FA-10J (or approved equivalent)Choice of the actuating system: plunger, roller, spindle-mount lever, and two lever-style actuator head rotatable in 90° incrementsIP65 glass-reinforced thermoplastic switch housing; addition of screw to wiring chamber door to minimize defeat
