Proximity sensors are constructed by shaping and sealing a magnetic spring tube connected with wires. Switching action will occur when a magnetic object is in proximity. It is usually used as a position sensor. Proximity sensors are widely used in measuring instruments, office automation equipment, household supplies, security and safety equipment, and transportation equipment.
