- 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 010Vdc 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.

- Electrical angle can be 3 turn, 5 turn, 10 turn, 15 turn and 20 turn.
- Mechanical angle can be 10 turn or 20 turn.
- Shaft on both sides and Threaded shaft available.
- Metal housing housing version available in 48mm dia.
- Terminal Block, Turrets, Fly wire or cable output version available.
BENEFITS
- Non Contact Linear Position Sensor based on Hall Effect Tenology.
- Accurate Linearity upto 1% F.S. or 0.5% F.S (on request)
- Extremely Long Life.
- Extremely Compact in Size.
- Short Circuit, Overvoltage and Reverse polarity protected.
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.

Serial Peripheral Interface Sensor
The RHSS12-XSPI is a Absolute encoder which acts as a slave and communicate with master micro controller as per the standard Protocol of SPI.
As per standard protocol of SPI RHSS12-XSPI communicate with master protocol when the MOSI pin is active high or 3FFF hex data is sent on the bus and the CS pin need to toggle from low to high for only one clock pulse.
RHSS12-XSPI communicate in 16 Bit of Transmission. After each cycle of communication it is compulsory to toggle CS pin from high to low.
RHSS12-XSPI has a provision of Dual Output first SPI communication and PWM mode of communication 14 Bit and 12 Bit of Resolution respectively.
Number of sensors can be connected in daisy chain mode of 4 wire or (n+3 wire connection). please contact Mr. Pavan Kinariwala(pavankinariwala@gmail.com) for more information on the same.
