Azbil VCL-50 Waterproof Vertical Limit Switches use 2 sets of SPDT built-in switches to enable use as a 2-point detection (center neutral). Two different internal switches operate according to the direction (cw or ccw) of the actuator. A single switch can detect two points (valve upper/lower limit, fully open/closed etc.) The limit switches have high sensitivity (pretravel=10°, movement differential=3°).OverviewIn center neutral operation type, according to hand of cut (clockwise or counterclockwise) of the actuator, respectively internal switch work.Two points of the upper/lower limit, fully-close/open and etc. on valve drive parts can be detected with one limit switch.It has excellent seal, season resistance, and corrosion resistance.It is high sensitibity so that maximum of P.T. (petravel) is 10° and the maximum of D.T. (differential travel) is 3°.
