1、Inductive proximity switch is a position switch that can be operated without mechanical direct contact with moving parts. When an object approaches the sensing surface of the switch to the action distance, it can be operated without mechanical contact an 2、The proximity switch is a kind of on-off sensor (i.e. contactless switch). It has the characteristics of travel switch and micro-switch, as well as sensing performance. It has reliable action, stable performance, fast frequency response, long application 3、Proximity switch, also known as contactless proximity switch, is an ideal electronic switch sensor. 4、When the metal detector is close to the sensing area of the switch, the switch can be contactless, pressure-free, spark-free, and quickly send out electrical instructions, accurately reflecting the position and range of the motion mechanism. 5、Compared with general mechanical travel switches, products have many advantages in these aspects, such as general range control, positioning accuracy, operating frequency, service life, convenience of installation and adjustment, and adaptability to hars
