Benefits

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.

Highest availability and unrivalled durability under harshest ambient conditions: Proven HeavyDuty design, double-sided bearing setup, HeavyDuty connection technology, highly robust sensing
Reliable in any environment: Extremely durable aluminum housing, outstanding corrosion resistance (category C4), long-term stable sealing concept, operating temperature up to +100 °C
Efficient protection against bearing damage: Double-sided bearing setup (where possible), generously dimensioned bearings with large bearing spacing, high bearing load reserve for large radial / axial shaft loads, no inductive shaft currents due to hybrid bearings with ceramic balls
Improved control quality and process control in the application: Interference-proof, precise sensing with Opto-ASIC, best electromagnetic compatibility
Reliable signal transmission over long distances: Powerful output drivers for cable lengths up to 350 m (HTL-P) or 550 m (TTL), signal transmission via optical fiber up to 1500 m
Standard explosion protection: ATEX certification Ex II 3G / 3D for Zone 2 for almost all devices, versions with ATEX / IECEx certification Ex II 2G for zone 1
Easy and flexible product selection: All common mounting types (hollow shaft, cone shaft, shaft with EURO flange B10), connection via terminal box / flange connector M23 / cable, output signals HTL-P / TTL
Large variety of designs and options: High-resolution up to 10 000 ppr, function monitoring EMS, redundant sensing, dual shaft for mounting of additional devices, twin encoders, encoders combined with centrifugal switch (FSL) or electronic speed switch (ESL), housing base B3
Convenient diagnostics for higher availability: Permanent supervision of numerous rotary encoder functions with function monitoring EMS, detection of connection errors already during assembly, shortening commissioning and error search

Applications

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:
