Motion Sensors Inc offers hall effect, variable reluctance, RF eddy current, amplified active, and magneto-resistive speed sensors. Their VR models include the premium series which are hermetically sealed with a heli-arc welded construction, two pin gold plated glass sealed connectors, with a temperature range from -450 to +450F.

Sensoronix makes speed sensors including hall effect and variable reluctance types, such as analog sine wave speed sensors, with an air gap of 0.005" to 0.150", speed range of 30 to 1000 inches per second, resistance of 40 to 2000 OHM, and a ferrous material target.

Motion Sensors offers variable resistance (VR), hall effect, amplified (Active), RF (Eddy Current), and magnetoresistive (MR) speed sensors. All speed sensor types have the option of ATEX certification for intrinsic safety.

Sensoronix manufactures variable reluctance (VR) and hall effect zero speed sensors. Hall effect zero speed sensors come in digital, digital to analog (D/A) converter, and digital speed and direction configurations. Variable reluctance speed sensors come in analog to digital (A/D) converter, analog (sine wave), and analog complimentry (dual sine wave) configurations.
