Overview

The relay contact five wire output proximity switch LJC40-2420GJ generates an AC magnetic field in the detection coil and detects impedance changes caused by eddy currents generated by the metal body of the object.

Product Introduction

A proximity switch is a type of position switch that can be operated through direct mechanical contact without the need for moving parts. When an object is in proximity to the switch, it can sense the distance of movement and drive a DC electrical device or provide a control command to a computer device. It is an ideal electronic switch sensor. Proximity switches are widely used in many industries, especially in industry. They are divided into several categories such as passive, photoelectric, and capacitive, and can accurately reflect the position and stroke of the machine's motion mechanism.

Selection:

1. Select the proximity switch type based on the detected object. If the detected object is a metal, an inductive proximity switch should be selected. If the detected object is a non-metal such as wood, plastic, paper, water, or smaller and thinner metals, a capacitive proximity switch should be selected.

2.The choice of appearance can be determined based on the installation position of the proximity switch, usually including cylindrical proximity switches, square proximity switches, and circular proximity switches. If choosing a cylindrical shape, one should consider the required diameter, and if choosing a square shape, the diameter of the detection surface should also be selected.

3. Selection of sensing distance: Generally speaking, the detection distance of proximity switches is relatively short, commonly ranging from 1-50mm. The longer the detection distance, the larger the detection surface and the higher the price.

4.The position of the sensing surface usually includes front-end sensing, upper end sensing, and inner hole sensing options;

5.Line length selection, configure the length of the connecting cable to be2Rice. If a longer connecting wire is needed, it should be explained to the manufacturer before ordering. However, do not add an extension wire after setting the proximity switch, as this can easily lead to unstable output signals of the proximity switch.

6. Output working voltage selection, usually available in DC 24V or AC 250V options;

7.The selection of output methods usually includesNPN-Normally openNPN-Normally closedPNP-Normally openPNP-Normally closed2The line is always open,2Line normally closed, DC3Linear, DC4Line optional;
