Marsh Electronics offers a variety of magnetic sensors. The MP1001 Series magnetic position sensors have electrical immunity protection and are compatible with unregulated power supplies.  Hall-based magnetic proximity sensors include the MP1014 Series in low-profile, flange-mount housing, MP1005-MP1007 Series in adjustable, threaded housing, and MP1013 Series in snap-fit mounting.

Sensor Solutions manufactures non-contact magnetic sensors for the industrial, agricultural, solar energy, wind turbine, and related markets. They offer single-channel gear tooth speed sensors that use Hall effect technology to produce a digital output as gear teeth pass by the sensor, and Hall switch sensors and magnetoresistive switch sensors to determine linear and rotational speed, as well as direction and position, of targets. Single-channel target tracker gear tooth sensors, which send digital pulses in the presence of metal without the rotational alignment of a Hall effect sensor, can be used to determine speed on bolt heads, holes in gears, etc. In addition to these three options, Sensor Solutions offers more than a dozen others, include quadrature 2-channel gear tooth sensors, speed direction gear tooth sensors, speed direction quad gear tooth sensors, dual output Hall switch sensors, Hall latch sensors, and digital and analog ferrous metal detection sensors.
