ASCO 494 Miniature T Shaped Magnetic Detectors For Air Cylinders – ASCO Numatics Joucomatic
T&D – ASCO Numatics Authorised Distribution Channel.
ASCO Numatics Joucomatic Cylinders.
ASCO 494 miniature T shaped magnetic detectors are universal detectors for any of the ASCO range of air cylinders and actuators.
A permanent magnet which is mounted on the piston of the air cylinder activates the reed switch of the non-contact magnetic position detector fastened on the outside of the non-magnetic cylinder barrel.
ASCO Numatics Joucomatic 494 cylinders are available as magnetic detectors for air cylinders with following options :
- Miniature “T” shaped detectors for air cylinders with grooves- 3 wires – magneto-resistive type
- Miniature “T” shaped detectors mounting kits for profiled, tie rods and round cylinders
- Miniature “C” shaped detectors for air cylinders series 441 with grooves – magneto-resistive type (MR)
ASCO products include an extensive range of solenoid valves, angle body piston valves, valve manifolds, cylinders, filters, regulators, lubricators and accessories.

➡ Did you know? ASCO founded in 1888 was acquired by Emerson in 1985. In 1988, Emerson purchased Joucomatic, Europe’s leading pneumatic valve manufacturer and added it to the ASCO family. In 2008, Emerson merged the North American operations of its ASCO and Numatics companies to form ASCO Numatics. In 2016, ASCO and Numatics global operations were unified under the ASCO brand.
