Description

LJ18A3-8-Z/BX 8mm Approach Sensor Inductive Proximity NPN NO Switch DC 6-36V

This LJ18A3-8-Z/BX 8mm Approach Sensor Inductive Proximity NPN NO Switch DC 6-36V can detect a distance up to 8mm.

Product description

The LJ18A3-8-Z/BX  Proximity sensor that detects nearby metal, including aluminum foil; a great solution for heated bed calibration.

The LJ18A3-8-Z/BX proximity sensor Can detect the metal at 8mm distance with great precision. This allows you to accurately measure the distance to an aluminum heated bed for example. If you are using a glass plate as your print surface, you can use aluminum foil right below the glass, which will also be detected by the LJ18A3-8-Z/BX  proximity sensor (mirrors however are not detected). The LJ18A3-8-Z/BX proximity sensor is equipped with a small red detection LED, indicating a nearby object. The LJ18A3-8-Z/BX proximity sensor has an M18 threading and includes a nut for easy mounting to your 3D printer or CNC machine.

The LJ18A3-8-Z/BX proximity sensor is a PNP Normally Open (NO) type of proximity sensor. This means that the signal lead will output a positive voltage (same as the input voltage) when a metal mass is detected. When nothing is detected, the signal is equal to ground.

Most modern 3D printer firmwares have some sort of auto bed leveling procedure available, but you will need to enable it. You can use this LJ18A3-8-Z/BX proximity sensor as the z_min_endstop for example, replacing your current end stop. Most firmware will also use the min endstop as a probe, but some allow a separate probe to be defined.

This LJ18A3-8-Z/BX proximity sensor operates at 6-36V, so as the signal voltage is the same as the input voltage, also the signal will be 6-36V. You will need to down-convert the voltage to acceptable level for your electronics. Please see the linked schematic on how to connect this sensor to the endstop pins of your electronics board.
