The HOG9 / POG9 series is an extremely wide and versatile product family of incremental HeavyDuty rotary encoders. It is based on the enormous experience of the HeavyDuty world market leader, and always offers you a proven solution for your application.
HOG9 / POG9 rotary encoders operate reliably and permanently in 24/7 operation even in the toughest conditions. They make a significant contribution to the prevention of failures and high standstill costs and thus make a key contribution to the high availability of your machine or system.
Incremental HeavyDuty encoders provide information on speed and angular position. Their resolution is expressed as the number of pulses (square-wave signals) and the sinusoidal (Sin/Cos) signals per revolution, which the rotary encoder transmits to the controller with each revolution of its shaft. Sin/Cos signals can be interpolated in a controller or in a controller to increase the resolution.
The upstream control identifies the current speed by the pulse numbers counted within a defined time period, while the current position information is identified by the counted pulses or Sin/Cos periods, respectively. At system power-on, a reference travel is required since the encoder information may have been lost during power off and further to eliminate any incorrect result caused by any shaft rotation performed during power-off.
Incremental HeavyDuty encoders are designed for maximum robustness and durability, with enormous mechanical reserves to ensure reliable performance even in the harshest environments:
