Sensors for T-slot cylinders

Reed contact cylinder sensors for T-slot

Your Benefits

  • A sensor for a wide range of applications: The sensor design fits into all standard T-slots used around the world, regardless of the cylinder profile or make
  • Simple mounting: Thanks to the retaining ribs on the side, the sensor holds its position even before the screw is tightened, ensuring that it does not fall out
  • Fast mounting: The sensor is fixed quickly and securely in the slot simply by rotating the fixing screw a quarter turn
  • The rugged fixing screw holds the sensor in the required position, even when exposed to shock and vibration
  • It is easy to replace the sensor during servicing without removing the end caps


Reed contact cylinder sensors for T-slot

The SICK RZT7 cylinder sensor with reed contact reliably detects the piston position in pneumatic drives. The RZT7 can be mounted directly into all cylinders with standard T-slots. SICK also has an extensive range of adapters which enable the RZT7 to be used with other cylinder types. The RZT7 is characterized by its simple mounting principle: Insert the sensor into the slot and rotate the fixing screw a quarter turn to fix it securely to the cylinder.

At a glance
  • Can be used in all standard cylinders, linear slides, and grippers using the T-slot and – with the help of adapters – in round rod, tie-rod, and profile cylinders, and cylinders with a dovetail groove
  • Drop-in mounting from above simplifies handling and assembly
  • Combined fixing screw (hexagon socket screw and slotted screw)
  • LED for indicating the output state (depending on type)
  • Enclosure rating: IP 67
  • Supply voltage up to 230 V
