Incremental encoder along with Absolute encoder

Absolute encoder with Cable output and D-Shaft

Flange mounting

- Rotary Rugged Sensor is a transducer to detect the angle / speed of the system which correspondence to the rotary motion of the shaft.
- Rotary Rugged Sensor is based on contactless Magnetic technology and hence has a very long life.
- This Transducer can be customised in several ways to have different Electrical angle, Voltage Output, Current Output, Digital Communication signals such as SSI, SPI, I2C or Incremental Output.
- Rotary Rugged Sensor housing and Sensor Shaft can be modified based on the requirement
- This Transducer has a Optional of Having Span and Offset settable with TWO trim pots given at the back of the system for certain variant.
- The Protection class of the standard sensor is IP65 However the same can be increased subject to the requirement of the user.

Mounting
There are two types of Mounting Provision available.
1) Servo Mount: Servo mount Groove is available to fix the Transmitter for which 40mm of hole in a plate of minimum 2 mm thick need to be made along with clamp to fix the transmitter. EMC48 encoder mounting clamps are available for the same.
2) Top Mount: 3 M3 Threaded Screws at 120deg apart in a PCD of 30mm dia is given with 5mm dip. For which 20mm of hole in a plate of minimum 1mm thick is necessary. To have the best performance of the sensor the Radial load on the sensor should be minimum. To elaborate the Misalignment between the Axis of the transmitter and Shaft should be nil.

RHSS48-I2C is a Absolute encoder which acts as a slave and communicate with master micro controller as per the standard Protocol of I2C. It is also known as Two Wire Communication.
RHSS48-I2C communicate in 8 Bit of Transmission.
As per standard Protocol each slave (RHSS48-I2C) has a Slave address of 7 bit which is being made of two Address Pin 1 and 2 while the remaining 4 bits are always 0 and MSB being 1. Address pin 1 and 2 are Least significant bit of
Address. Hence we can use maximum of 4 such sensors in a Daisy chain mode of communication with slave address
as 1000001 / 1000000 / 1000011 / 1000010.
RHSS48-I2C has a provision of Dual Output first I2C communication and PWM mode of communication 14 Bit and 12 Bit of Resolution respectively.
RHSS48-I2C communicates the angle information in two cycles. By sending the register address 254 and 255. To
have the complete angle information we need to eliminate two most significant bit (6 and 7) of the data byte we receive after sending register address 255.
RHSS48-I2C will communicate the angle information in below pattern

The RHSS48-SPI is a Absolute encoder which acts as a slave and communicate with master micro controller as per the standard Protocol of SPI.
RHSS48-SPI communicate in 16 Bit of Transmission.
As per standard protocol of SPI RHSS48-SPI 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.
After each cycle of communication it is compulsory to toggle CS pin from high to low.
RHSS48-SPI 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 (potel@potentiometer.in) for more information on the same.
RHSS48-SPI will communicate the angle information in below pattern.
