Sensors for C-slot cylinders

Your Benefits

  • A sensor for a wide range of applications: The sensor design fits into all standard C-slots used around the world, regardless of the cylinder profile or make
  • Quick and easy mounting using an Allen key or flat-head screwdriver
  • Low maintenance costs as the sensor is resistant to shock and vibration, meaning it does not slide about in the slot
  • Saves time on initial installation and when replacing devices as the sensor can be easily inserted into the slot from above. The end caps of the cylinder do not have to be removed.
  • Very rugged housing with enclosure rating IP 67, IP 68, or IP 69K extends the service life of the sensor


The RZC1 magnetic cylinder sensor with reed contact from SICK is the flexible solution for detecting the piston position in pneumatic actuators. The RZC1 can be mounted directly into all cylinders with standard C-slots. SICK also has an extensive range of adapters which enable the RZC1 to be used with other cylinder types. The RZC1 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. Furthermore, the RZC1 is available in a range of variants up to an enclosure rating of IP 69K. This ensures the sensor has a long service life and reduces maintenance costs.

At a glance
  • Can be used in all standard cylinders, linear slides, and grippers using the C-slot and – with the help of adapters – in round rod, tie-rod, and profile cylinders
  • Drop-in mounting from above simplifies handling and assembly
  • Combined fixing screw (hexagon socket screw and slotted screw)
  • LED for indicating the output state
  • Enclosure ratings: IP 67, IP 68, IP 69K
  • Supply voltage up to 120 V DC
