The HEIDENHAIN ERN 120 incremental single turn rotary encoder is designed for large shaft applications, featuring an integral bearing, hollow shaft and mounted stator coupling with an IP64 protection.

The HEIDENHAIN ERN 120 rotary encoders have an integral bearing and a stator coupling which connects directly to the measured shaft. The ERN 120 series rotary encoders offer a high dynamic performance and natural frequencies with the following features…

• Hollow through shaft options Ø 20mm, Ø 25mm, Ø 38mm and Ø 50mm
• Single turn encoder
• TTL quadrature incremental signal
• Line counts from 1000 to 5000
• Single reference mark
• System accuracy is 1/20 of grating period
• M23 flange socket or attached cable
• Permissible axial motion of measured shaft is ±1.5mm
