Overview

A proximity switch is a type of switch type sensor (i.e. contactless switch) that has both the characteristics of a travel switch and the performance of a sensor. It has stable and reliable performance, fast frequency response, long service life, strong anti-interference ability, and is waterproof, corrosion-resistant, and shockproof.

Product Details

Proximity switch N08-M18-CSA6H (cement casting component)It is a new type of four wire integrated proximity switch DC stable voltage supply with 10-30VDC, which can be used to detect various metal bodies. It has high sensitivity, fast frequency response, high repeat positioning accuracy, short transient process, high output power, good emergency characteristics, stable and reliable operation, and long service life.

Proximity switch N08-M18-CSA6H (cement casting component)The stainless steel cylindrical threaded bracket is installed with a switch chamber filled with resin, which is fully enclosed and has characteristics such as vibration resistance, corrosion resistance, waterproofing, and oil resistance. When an object approaches a certain distance from the surface of the induction switch, it does not require mechanical contact or any pressure to make the switch operate, thereby driving DC power or providing control instructions to the computer (PLC) device.

Working Principle:

Proximity switch N08-M18-CSA6H (cement casting component)It belongs to a position sensor with switch output, which consists of an LC high-frequency oscillator and an amplification processing circuit. It uses a metal object to generate eddy currents inside the object when it approaches the oscillation induction head that can generate an electromagnetic field. This eddy current reacts on the proximity switch, causing the oscillation ability of the proximity switch to decay, and the parameters of the internal circuit to change, thereby identifying whether a metal object is approaching and controlling the on or off of the switch. The object that this proximity switch can detect must be a metal object.

Selection of proximity switches:

1. Selection of proximity switch types

Inductive type is the first choice for detecting metals, capacitive type is preferred for detecting non metals, and magnetic proximity switches are selected for detecting magnetic signals.

2. Selection of appearance for proximity switches

Generally, cylindrical thread shapes are commonly used, and can be selected according to actual needs.

Cylindrical thread shaped proximity switch

3. Selection of detection distance

According to the needs, the manufacturer's manual usually indicates the detection distance.

4. Signal output selection

The AC proximity switch outputs an AC signal, while the DC proximity switch outputs a DC signal. Special attention: The current of the load must be less than the output current of the proximity switch, otherwise a conversion circuit should be added.

5. Selection of Switching Frequency

Switching frequency refers to the number of times a proximity switch switches from "on" to "off" per second. DC proximity switches can reach 200Hz, while AC proximity switches can only reach 25Hz.
