  • The Rotary Miniature Angle Sensor is used to detect the angle or speed of system which correspondence to the rotary motion of the shaft of the sensor.
  • 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 RHSS-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.
  • With wide range of Mechanical and electrica variant makes it a ideal product for the industry.

For best performance of RHSS-12 below points needs to be taken into consideration. 1) The hole in the panel should not be more than 9.5mm. 2) RHSS-12 should be mounted with Star washer given along with the product and perpendicularity

Magnetic Cross Talk

If two RHSS-12 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.
