The S pole and the N pole must act alternately before the output pin has a work or release change.
It has the advantages of small size, light weight, long life, easy installation, low power consumption, high frequency, vibration resistance, and no fear of dust and oil pollution. It is widely used in industrial automation technology, testing machines and information processing.
