Rotary Sensor Kit

  • The Rotary Sensor Kit is used to detect the angle / speed of system which correspondence to the rotary motion of the shaft of the sensor.
  • RSSK-12 is a complete disassembled kit for easy mounting and accurate mounting of sensor.
  • With disassembled kit it is very attractive for applcation which demands for extremely low torque
  • The Output signal correspondence to 0 to 360deg. This full range is programmable based on requirement.
  • Since the Product is based on Contactless Magnetic Technology it has very long life.
  • Endless Rotary sensor can be specially programmed to have 4,3 or 2 cycles in over revolution hence increasing the accuracy.
  • For modern microcontrollers RSSK-12 is capable to give output in 0 to 3.3Vdc,SPI, I2C, Quadrature, Incremental and to suppress the effect of Noise PWM output version is also available.
  • Variants
    • 12 bit resolution 0 to 3.3Vdc Analog Ratio matric Output.
    • 12 bit resolution 0 to 5Vdc Analog Ratio matric Output.

Magnetic Cross Talk

If two RSSK12 units are to be installed closer than 2 inch (measured between the center of both shafts), a magnetic shield, such as a small steel plate should be installed in between to prevent one encoder from causing small changes in reported position through magnetic field cross -talk .

Ordering Information



RSSK-12 is a Rotary sensor Kit comprises of mainly Three parts and the same can be mounted in three steps.

Step 1: Mounting of Shaft Holder : Push Fit the shaft holder on the shaft with maximum height of 5mm with (6.3 + 0.02mm) Shaft Diameter with a maximum radial play allowed of 0.2mm. Lesser the radial play higher the accuracy. Customization of the shaft holder is possible.

Step 2 : Mounting of Sensor Head : On the shaft holder keep the Sensor head such that the shaft holder goes inside the sensor head.

Step 3: Mounting of Disc : On the Sensor head insert the Mounting disc such that the step on the mounting disc faces towards the mounting plate and fasten the screw at a PCD of 19mm. Note you can rotate the sensor head prior to fixing the screw by energizing the encoder to desired position.
