Spectec offers a variety of magnetic speed sensors and Hall Effect position sensors. The Hall effect gear position sensors are dual output configurations that detect the direction and position of a target gear. They are also used for rotation profiling, angle profiling and field profiling.

Baumer offers a wide variety of sensors for different applications. Its non-contact inductive proximity sensors detect metal to ensure the movement and position of machine parts, valves, and gears, and its photoelectric sensors can measure objects several meters away, with an accuracy of a tenth of a millimeter. The ultrasonic sensor measures up to 2.5 m away, and features a high resolution of 0.3 mm. The company's magnetic sensors can be used to detect precisely rotary movements, up to 20,000 measurements per second, and its magnetic cylinder sensors can be used in areas of automation to detect the movements of pneumatic cylinders and register the position of pistons.

Melexis produces several Hall Effect devices useful for both movement and position sensing. The MLX90316 Rotary Position Sensor IC offers 12-bit angular resolution and 10-bit angular accuracy, and can be used for controlling headlamp position, side mirror position, and other similar applications. The MLX90324 Under-the-Hood Rotary Position Sensor provides 12-bit resolution on 360 degrees of rotation, and the ability to report current angle values in analog, digital pulse width modulation, or digital single edge nibble transmission. Finally, the MLX90333 Triaxis 3D-Joystick Position Sensor is able to sense any magnet moving in its surroundings, and is sensitive to the flux density applied both orthogonally and parallel to the IC surface.

Penny and Giles produces a wide range of linear position sensors, linear displacement transducers, and linear potentiometers that offer stroke length measurements from 0.2" to 196", using potentiometric, inductive, eddy current, and Hall Effect technology. They also offer rotary position sensors to provide angle measurements from 10 to 360 degrees, with environmental protection to IP68 and IP69K.

State Electronics builds rotary, linear, and multi-turn potentiometers and encoders. The custom selection starts with the 0.5-inch square, plastic and cermet modular Series 388 and 389; the 0.675-inch square, metal shaft and bushing Series 70; and the 0.675-inch plastic shaft and bushing Series 72. In addition, the company offers millions of combinations of modular and motorized potentiometers, with single, dual, triple, and quad modules, as well as customized switches, shafts, and terminals. They also offer precision potentiometers for heavy equipment and robotics and multi-turn potentiometers for accurate and stable control input, in addition to Milspec, linear motion, and Hall Effect devices.

Optek offers many choices for Hall Effect sensing technology, including bi-polar, ratiometric, and uni-polar options. Most of their products come with a minimum voltage of 4.5 and a maximum of 24. Operating points and release points are highly variable depending on the part number.
