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.

SICK manufactures magnetic proximity sensors and magnetic cylinder sensors. Proximity sensors are available in both cylindrical (MM) and square (MQ) configurations, with a maximum sensing range of 120 mm. Cylinder sensors are available in T-slot, C-slot, and other configurations.

VectorNav Technologies makes the VN-100, an orientation sensor that combines a 3-axis accelerometer, 3-axis gyro, 3-axis magnetometers, and a 32-bit processor. The unit comes fully calibrated for bias, gain, and misalignment, and is thus able to calculate orientation accurately over a 360-degree range at 200 Hz.

Balluff offers a variety of magnetic sensors, starting with inductive proximity sensors. These products emit alternating electro-magnetic sensing fields that trigger upon entrance of a metal target. Housing styles include standard and mini tubular and block styles, as well as cylinders  and large housings. The company also produces inductive distance sensors with Sn ranges from 2 mm to 50 mm, as well as magnetic field sensors that use magneto-resistive technology to detect piston magnets through the aluminum walls of pneumatic cylinders.

Cherry Corp. specializes in the production of magnetic proximity sensors, speed sensors, and rotary position sensors to meet the needs of OEM customers. Magnetic options include the MP2007 Series reed sensor that is omnipolar and can therefore be approached by a magnet from any angle, with an operate time of either 0.6 or 1 ms; the DS1101 Series solid state button-actuated sensor that uses Hall effect technology; and the VN1015 Series magnetically-activated digital vane switch that comes in an overmolded plastic housing with either 3-pin or 3-wire harness termination.

Infineon magnetic sensors are split into three subcategories: rotational speed sensors, Hall-effect switches, and position and current sensing. Rotational speed sensors are used in automotive applications like ABS, transmission management, and engine management, and available for 2- or 3-wire interfaces, as well as with or without direction detection and/or vibration suppression. The Hall switches are unipolar and omnipolar switches and bipolar latches that cover a wide range of applications, from position sensing to index counting. Features include voltage interface, 2-wire current interface, double latch for speed and rotation direction detection, and more. Finally, position and current sensing products start with linear Hall sensors, and end with GMR-based 360-degree angle sensors.

Using both Hall effect and variable reluctance technologies, Sensoronix magnetic sensors provide a range of sensor solutions to measure speed, direction, position, and proximity. Their basic Hall effect zero speed sensors provide digital output with constant amplitude signal, regardless of speed variation. With an airgap from 0.005" to 0.120", it measures a speed range from 0 to 15 KHz (20 KHz optional). The digital proximity sensor comes with sinking NPN or sourcing PNP output; its magnetic release point is 140 Gauss Nom. and its magnetic operate point is 180 Gauss Nom. Two Hall effect linear position sensors are also available at 0 to 5 VDC and 0 to 10 VDC, as well as analog speed sensors (sine wave), analog to digital converter speed sensors, and analog complimentary variable reluctance speed sensors (dual sine wave).

TTI carries Honeywell magnetic speed and position sensors that use Hall effect, magnetoresistive, and variable reluctance technology. Available speed sensors start with the 1GT gear tooth sensor with an operating speed >100 KHz for sensing ferrous metal targets, and end with the SNDJ Series, T4C double Hall effect sensor, which has a 1.5 mm sensing range and two back-biased Hall effect ICs that are zero-speed capable for use as a proximity switch. Position sensors include the bipolar Hall effect SS30AT, which offers reverse polarity protection and stable output over a -40 to +125 degree Celsius temperature range; unipolar Hall effect 103SR for position and RPM sensing in non-corrosive applications; and omnipolar magnetoresistive 2SS52M, which offers digital output in response to very low magnetic fields.
