Devices to detect the limit switch for short stroke compact cylinders and tie-rod cylinders


The sensors for Idroteck hydraulic cylinders are adaptable to short stroke compact cylinders and to tie-rod cylinders for the magnetic series. They are divided according to the type of voltage, power, contact type and temperature limits. To fix the sensor, the compact cylinders already have a cavity specifically created to insert the device, while the tie-rod cylinders need a sensor holder bracket.


REED sensors


The limit switch consists of a Reed contact drowned in synthetic resin; as a magnetic field approaches, the contact closes generating an electrical signal.

  • REED contact SCTW for T° up to 120°C with 2 wires;
  • SCT REED contact SCT for T° up to 85°C with 2 wires;
  • REED contact SCTM8 for T° up to 85°C with 3 wires.
