Mounting

For best performance of LHS-X-18X18-XX below points needs to be taken into consideration.
1) The Pushing force to the shaft need to be perpendicular to the linear motion.
2) The mounting of the sensor should be with minimum 4 clamps in a as flat surface as possible. Clamps will be mounted by 2 M4 screw and Nut assembly at a distance of 29mm from each other. MC-18X18 are availibale for the same.

Magnetic Cross Talk

If two LHS units are to be installed closer than 2 inch (measured between the center of both shaft),a magnetic shield, such as a small steel plate should be installed in between to prevent one encoder from causing smal l changes in reported pos ition through magneti c field c ros s -tal k .

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.
RHSS12-XSPI will communicate the angle information in below pattern.
