Stainless Steel 4-20mA Shaft Speed Sensors

Product Announcement from Electro-Sensors, Inc.

Stainless Steel 4-20mA Shaft Speed Sensors-Image

The patented ST420-LT and ST420-DI are 2-wire, loop-powered, 4-20mA analog output shaft speed sensors. They detect passing magnets of a shaft-mounted pulser disc or wrap and output a smooth, continuous 4-20 mA analog signal in direct proportion to shaft rotation speed. The ST420-LT and ST420-DI have integral conduit attachments, are NEMA 4X, IP65 and Dust Ignition-proof for Class II, Div I (E, F, G) hazardous locations.

All models have rugged stainless-steel M18x1 housings for harsh environments and require no user calibration. Custom measurement ranges are available upon request.
