Model No.
ALS200D
Overview
ALS200D Series Limit Switch Box (Valve Monitor) is a rotary position indication device, using two reed switches and two permanent magnets. They are encased in a plastic housing for protection and ease of mounting. The reed switches mounted on the top of actuator and the permanent magnets mounted on the stem of the actuator. Each switch and magnet complete a circuit when the actuator / valve closed / opened. The circuit breaks when the actuator / valve opened / closed. This device can sense machanical position (on/off) of valve for remote PLC or PC indication. The visual indicator on the top of the device can also clearly display the valve position for local detection.
