Baumer Hübner HeavyDuty incremental encoders are characterized by the following excellent features:

Robust construction with solid light alloy housing for high vibration and shock proof protection.
Bearings at both ends of the shaft, where construction permits.
Short-circuit proof power transistors with peak currents up to 300 mA for line driving over long cables with HTL-signals or optional TTL-signals to RS-422.
High Electromagnetic Compatibility (EMC), tested to IEC 801-4.
Protection against shaft currents due to insulated ball bearings, in some devices.
Incremental encoders without bearings for drives with large axial play or high speeds.
Through-hole hollow shaft, also available in Sinus-Technology and in explosion proof execution "II 2 G EEx de IIC T6".
Wide range of program with standard EURO-Flange B10.
Rear shaft option for mounting of other devices.
Combinations with common shaft:
- Incremental encoder + Incremental encoder (Twin Tacho),
- Incremental encoder + Analog-Tacho,
- Incremental encoder + Speed Switch.
