Omron H8PS Counter, 24 V dc

The Omron H8PS series digital counter is an LCD display electronic panel mount cam positioner. This counter is logic input, flush mounting and 8 PNP transistor output device. The counter has a voltage rating of 24VDC. It is equipped with useful functions for switching encoder rotation direction, designating the point of origin.

Construction:
The electrical signal of the absolute encoder is directly related to the angle of the shaft. The mechanical angular position is sensed by non-contact optical elements, therefore without wear. The output of an infrared diode is transmitted through a transparent code disc and diaphragm. The light/dark pattern is converted to an electrical signal by an array of photodiodes. The same code occurs only once per revolution. This encoder is defined as a single turn encoder.

Output circuit

Types of code
Any electronic code is made out of a combination of bits. Each bit is characterised by a low (0) or high (1) signal. The combination of a series of bits is called a binary word. Several binary words make a code.

Single-step code - Only one bit on the parallel output changes state at any given point in time. There is no possibility of any concurrent state changes. Single-step code is very versatile and can maintain accuracy even allowing for slight misalignments of the disc and scanning device
