LJ12A3-4-Z/BX Inductive Proximity Sensor Detection Switch NPN DC6-36V
This Inductive Proximity Switch is widely used in automatic control industry for detecting, controlling, and noncontact switching. When proximity switch is close to some target object, it will send out control signal.
Also can be used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial etc.
These are a popular choice for 3D Printers, being ideal for bed leveling.
Inductive proximity sensor is a great way to precisely detect when a metal object is at a given distance. Since this is a non-contact sensor, it is ideally suited to situations where dust, dirt, or liquids may be present. This specific sensor triggers when the sensor tip is 4mm away and features an LED that also illuminates when the sensor is tripped. Mounting this sensor is quite easy – it has a long threaded body allowing for a considerable adjustment.
