Two-wire vibration switch

Series 686A two-wire electronic vibration switch is a microprocessor that does not require moving parts or mechanical adjustments. It combines the reliability and dynamics of an electronic switch with the convenience of a mechanical switch. Magnetic adjustable vibration threshold electronically adjusts the threshold value while the switch is installed on running equipment through a magnetically activated sensor. This allows for immediate installation and protection with no need for equipment shutdown.
