Feature: 1. Proximity switch is a kind of switch-type sensor (i. e. contactless switch), which has the characteristics of travel switch and micro-switch as well as sensing performance. 2. The switch is reliable in operation, stable in performance, fast in frequency response,long in service life, strong in anti-interference and so on. It is waterproof, shockproof and corrosion resistant. 3. When the metal detection body is close to the induction area of the switch, the switch can be no contact, no pressure, no spark, and quickly send out electrical instructions, which accurately reflect the position and stroke of the moving mechanism. 4. The switch has the advantages of high positioning accuracy, high operating frequency, long service life, convenient installation and adjustment, and strong adaption ability to the harsh environment. 5. Widely used in machine tools, metallurgy, chemical industry, light textile and printing industries. It can be used as position limiting, counting, positioning control and automatic protection link in automatic control system.
