Product Description

Free Shipping 3D Printer Inductive Proximity Switches LJ12A3-4-Z/BX Three-wire NPN Normally Open DC 6-36V Automatic Leveling

1. Function and use: 3D Printer automatic leveling platform

2. Detection distance: 4mm

3. Working voltage: DC 6-36V

4. The proximity switch Description:

Integrated proximity switches, also known as non-contact proximity switch, it plays after the oscillator oscillator generates an alternating magnetic field induced by the oscillator switch head and shaping amplifier, when the metal body close to the sensing area, the metal body a vortex to absorb the energy of the oscillation, the oscillation amplitude decreased stop vibration that enables proximity switches to achieve the purpose of reversing, by the shaping amplifier into binary switching signals, so as to achieve the purpose of detection.
This series of high-frequency oscillation type proximity switch, it is a non-contact, no pressure, no spark, quickly issued a detection signal to drive a relay or logic gates, it has a high sensitivity, fast frequency response, high repeat positioning accuracy, Shun change process short, high output power, anti-jamming performance, stable and reliable operation, long life, filled with resin inside the switch to fully enclosed, with vibration-resistant, corrosion-resistant and waterproof characteristics.

5. How it works:

Proximity switch consists of three parts: oscillator, switch circuit amplifier output circuit. The oscillator generates an alternating magnetic field. When the metal target close to this field, and reaches the induction distance, eddy currents in the metal target, causing oscillation damping, as well as to stop vibration. Oscillator stop vibration and variations is processed stage amplifier circuit and converted into a switching signal to trigger the drive control device, so as to achieve the non-contact detection purposes. The closer the target from the sensor, the sensor nearer the target, the greater the damping coil; the greater the damping, the less the current sensor oscillator inductive proximity switch current consumption is reduced with a metal target distance. decreases.
