Vibration switches offered by IMI Sensors

IMI offers a variety of vibration switches for protecting critical machinery from costly destructive failure by initiating an alarm or shutdown when excessive vibration of the machinery is detected. These devices can also be used to warn of the absence of vibration, such as when a conveyer ceases to function due to a broken drive belt. Vibration Switch Brochure PDF (636 kB)

Series 685B: Electronic, AC or DC power, dual switches
This precision electronic vibration switch is AC or DC powered, utilizes an on-board or remote accelerometer, provides two relay or triac outputs, generates a 4 to 20 mA vibration output signal, and offers an analog vibration signal for FFT analysis and fault diagnostics.

Series 686A: Electronic, universal power, single switch
This revolutionary two-wire electronic switch offers the simplicity of a mechanical switch with the precision of an electronic switch. The unit operates from universal power that is scavenged from a load's power source. It is microprocessor controlled, has a built-in accelerometer, installs easily with a single stud, and has the smallest footprint of any vibration switch on the market.

Series 685AX1: Electronic, DC power, single switch
This general-purpose electronic vibration switch is DC powered, utilizes an on-board accelerometer, and offers a single, 5-amp, Form C relay output.
Series 685: Mechanical, single switch
This mechanical vibration switch is available in either in a NEMA 4 (IP66) or explosion proof housing, and offers a single, 5-amp, Form C relay output.
