Mounting

Two major points needs to be taken into consideration while mounting AHS-Rf.

  • The co eccentricity of motion of shaft holder over sensor head as per the marking. This determines maximum linearity and performance of the sensor.
  • The Air gap between the Shaft holder and sensor head needs to be stricly mainted to 1.5mm to have best linearity. Sensor will perform upto 5mm gap. For longer airgap please contact us.

Two Wire Communication

The RTS-Rf-635I2C 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.

RTS-Rf-635I2C communicate in 8 Bit of Transmission.

As per standard Protocol each slave (RTS-Rf-635I2C) 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.

RTS-Rf-635I2C has a provision of Dual Output first I2C communication and PWM mode of communication 14 Bit and 12 Bit of Resolution respectively.

RTS-Rf-635I2C 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.

RTS-Rf-635I2C will communicate the angle information in below pattern

Serial Peripheral Interface

The RTS-Rf-635SPI is a Absolute encoder which acts as a slave and communicate with master micro controller as per the standard Protocol of SPI.

RTS-Rf-635SPI communicate in 16 Bit of Transmission.

As per standard protocol of SPI RTS-Rf-635SPI 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.

RTS-Rf-635SPI 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.
