Problems solved by technology

However, the proximity switch is clamped by the elastic clip groove, which is not stable enough and is prone to fall off. At the same time, the installation height of the proximity switch cannot be adjusted. It will be in contact with the collision object, and there will still be some damage. The connecting wire of the proximity switch is not bound by a tightening device when placed, and it is easy to cause wiring confusion

Abstract

The invention discloses a capacitive proximity switch convenient to install including a switch shell, a connector lug is fixedly installed at one end of the switch shell. An inductive head is fixedlymounted at the other end of the switch shell; the outer surface of the connector lug is connected with a connecting wire; a portable fixing device is connected to the position, close to the middle, ofthe outer surface of the switch shell, a buffer protection device is connected to the outer side of the inductive head, a wire bunching device is connected to the position, close to the outer side ofthe connecting wire, of the outer surface of the connector lug, and a telescopic mechanism is arranged on the portable fixing device. The invention relates to a capacitive proximity switch convenientto install. According to the capacitive proximity switch convenient to install, a proximity switch can be conveniently installed and fixed, meanwhile, the installation height of the proximity switchcan be conveniently adjusted, an induction head of the proximity switch can be buffered and protected, meanwhile, the induction head does not make direct contact when collided, and a connecting wire of the proximity switch can be tightened.

Description

technical field [0001] The invention relates to the field of proximity switches, in particular to a capacitive proximity switch which is easy to install. Background technique [0002] Proximity switch, also known as contactless proximity switch, is an ideal electronic switch sensor. When the metal detection body is close to the sensing area of ​​the switch, the switch can quickly issue electrical instructions without contact, pressure, and sparks, and accurately reflect the position and stroke of the motion mechanism. Even if it is used for general stroke control, its positioning accuracy and operation The frequency, service life, convenience of installation and adjustment, and adaptability to harsh environments are incomparable to ordinary mechanical limit switches. It is widely used in machine tools, metallurgy, chemical industry, textile and printing industries. In the automatic control system, it can be used as the link of limit, count, position control and automatic p...
