Yaskawa offers a range of magnetic sensors, featuring the dustproof, flood-tight Bestact magnetic proximity switch. These switches utilize  Bestact logic and inductive rated (0.5 and 0.125 Hp) reed switches for locations up to 510 degrees Fahrenheit, with sensing distances up to 4.33". They can also handle corrosive, dirty, extreme temperature, and gaseous Class I, Division II hazardous location environments.

Euchner-USA offers magnetic sensors for a variety of applications. Inductive single and multiple limit switches are non-contact sensors that control and monitor machinery and industrial equipment, and actuate only upon detection of metal. Two operating voltages are available: 10-55 VDC and 20-250 VAC.

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.

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.

The GLS magnetic proximity sensor is available from Omron. With a permanent magnet used to operate the reed switch, the sensor is ideal for detecting opening and closing doors. The GLS has a 15 mm sensing distance, ambient temperature range from -20 to +60 degrees Celsius, and ambient humidity range of 35% to 85% (with no condensation).

Phoenix America carries magnetic speed sensors and magnetic proximity sensors. The former can be used to determine rotational speeds from 0 to 100 kHz with very high resolution, and in almost all industrial environments (e.g., dirt, grease, water splashes, etc.). They come magnet-actuated, gear-actuated, or variable reluctance. With similar environmental tolerances, proximity sensors determine the location or passage of a target moving up to 100 kHz with rapid response times. Operation methods include permanent magnet-, ferrous material-, and inductive material-actuation.

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).

Canfield Connector offers several magnetic sensors for different application needs. The Series 7GL and 7HL proximity sensors provide 85 Gauss sensitivity and are operational up to 30 G shock and 20 G vibration; because the 7HL is meant for hazardous locations, it is also NEMA 1, 4, and 13 rated. Reed and electronic magnetic sensors are also available under the Series 8, from the compact 8D that senses pneumatic cylinder position, to the IP67-rated 8E linear actuator magnetic sensor for harsh industrial applications. Another magnetic sensor is the Series 9C, a compact, universal, magnetically-operated proximity switch commonly used on aluminum, extruded profile type linear actuators, equipped with magnetic pistons; it is available in standard 9 ft. PVC wired or optional 8 mm quick connect.

Pepperl+Fuchs offers non-contact, inductive proximity sensors for the detection of metallic objects in machinery or automation equipment. Standard features include smooth or threaded stainless housings, polarity reversal and short-circuit protection, LED status indication, and M8, M12, or terminal connection styles. Capacitative sensors come in 12, 18, and 30 mm cylindrical styles, with some approved for use in hazardous areas. Magnetic field sensors are housed in M12 style standard, but also in a non-contact, piston detection sensor for use with steel hydraulic cylinders.

Carlo Gavazzi offers a comprehensive range of magnetic sensors for use in proximity detection applications. A wide variety of styles are available, including rectangular, cylindrical, and slotted, as well as special coded magnets and sensors for use in safety applications. These sensors are common to elevator, gate control, level detection, and access control applications.

Magnetic proximity sensors from Fargo Controls feature high operating distances, threaded metallic cases, hermetic sealing, and IP67 protection. Circular sensors come in 6.5, 8, 10, and 12 mm diameters and are housed in nickel-plated brass; rectangular sensors come with 10 mm standard operating distance and are housed in anodized aluminum and plastic.

Jameco Electronics sells Cherry magnetic speed and proximity sensors. Examples of stocked products are as follows: the AS Series reed sensor, which is an omnipolar, magnetically activated switch; the MP1013 Series snap-fit magnetic proximity switch with panel mounting and -40 to +85 degree Celsius operating range; the MP2007 Series 2-pin magnetic sensor; and the VN1015 Series digital vane switch sensor with either molded vane or 6" leads.
