Incremental HeavyDuty encoders HOG10 / POG10

The HOG10 / POG10 series is the most 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 an unrivalled robust and durable solution for your application.

HOG10 / POG10 rotary encoders operate reliably and permanently in 24/7 operation even under 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 deliver speed and angular information. Resolution defines by the number of pulses per revolution  (square signals) respectively the number of sine wave periods (Sin/Cos signals) per revolution. With every shaft turn, the encoder transfers the  information to the upstream control. Higher resolutions are achieved by interpolation of the Sin/Cos signals, either in the control or by using interpolation controllers.

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 respectively Sin/Cos periods. 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 while the system was not live.

Incremental HeavyDuty encoders are designed for maximum robustness and durability, with enormous mechanical reserve capacity to ensure reilable performance even in the harshest envrionments:

• Steelworks and rolling mills
• Port installations and crane technology
• Hoists and lifting platforms
• Underground and open pit mining
• Materials handling equipment
• Giant motors and generators
• Wind turbines
