Features: Proximity switch is a position sensor with switch output that can be connected with microcomputer It also can drive directly from, electromagnetic relays, counters and contactor to achieve automatic control purposes It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching. When proximity switch is close to some target object, it will send out control signal. It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial etc. Specification: Product name:Capacitive Proximity Sensor Switch Shell material : metal Model: LG18A3-10-J/EZ NO, LG18A3-10-J/DZ NC(Optional) Detection distance: 10 mm Detection object: strong magnetism Working voltage : AC/DC within 0-250vAC Output mode : two wire normally open( LG18A3-10-J/EZ )/two wire normally close(LG18A3-10-J/DZ ) Output current : 200mA Diameter:18mm Weight: Approx.77g/2.7oz Package list: 1 x Capacitive Proximity Sensor Switch
