Fargo Controls offers inductive, capacitative, magnetic, and photoelectric proximity sensors. Inductive models are constructed in many diameter sizes from 4 to 30 mm; in rectangular shapes; and in ring configurations with 5 to 100 mm hole sizes. Operating distances are as low as 0.8 mm and as great as 10 to 60 mm adjustable. Capacitative sensors are available in 18, 30, and 40 mm diameter sizes that have sensing distance ranges from up to 5 mm to 35 mm. Lastly, magnetic sensors for detecting magnets instead of metals are offered in 6.5, 8, 10, and 12 mm diameters or in a rectangular shape, while the photoelectric sensors come in standard 18 mm diameter with a 1,500 cm through-beam.
Keyence features three series of proximity sensors. The EM Series is an amplifier-in-cable compact proximity sensor that has a sensor head diameter as small as 3 mm for the cylindrical type and M5 for the threaded type. Next is the self-contained EZ/EV Series proximity sensor that offers an easy-to-see output indicator, flexible sensor head joint, and optional fluoro-polymer resin coating for spatter resistance. Last is the long-distance ES Series separate amplifier proximity sensor, which provides a detecting distance two times that of conventional sensors and a wide selection of sensor head types.
