Rotary multiturn Angle sensor is based on contactless magentic hall's Effect technology. (RHMS-22).- RHMS is in a compact dimension of 22mm OD with Maximum 10 turn (3600 deg) and 20 turn (7200 deg)
- The Output signal correspondence to 0 to maximum number of turns and degree. Standard being 10 turn and 20 turn. However we customise the sensor based on application requirment.
- Since the Product is based on Contactless Hall's effect Technology it has very long life, No effect of radial load upto certain extent, High vibration withstanding rating.
- The USP of the Product is with inbuild signal conditioner card with 0- 10Vdc output or PWM output or 0-5Vdc output. Beside this the back side slot allows the end user to precisely set the starting and end point.
- For angle measurement less than 360 deg we have sensors with model number RHSS12, RHSS22 and RHSS48.
- RHMS is a economical product with highly good accuracy and resolution of 12bit over a full range.

Mounting
For best performance of RHMS-22 below points needs to be taken into consideration.
1) The hole in the panel should not be more than 9.5mm.
2) RHMS-22 should be mounted with Star washer given along with the product and perpendicularity between the panel and axis of Sensor should be maintained.
Magnetic Cross Talk
If two RHMS-22 units are to be installed closer than 4 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.
