The HS6A Absolute Rotary Hollow Shaft Encoder fits shafts from 0.3″ to 0.6″ (8-15mm) and offers superior durability compared to ordinary optical absolute encoders. We also offer AV6A solid shaft flange-mounted models, HS6M magnetic absolute encoders, and HS40 severe-duty absolute magnetic encoders that fit shafts from 5/8″ to 1 1/8″ (16-30mm).

HS6A encoders feature superior shaft seals and bearings that remain sealed to keep contaminants out, even through temperature cycles or liquid sprays. Our encoder seals are protected by mechanical barriers to prevent flexing or failure, and our superior bearings outlast the competition, even when mounting stub shafts have increased runout.

Many competitive optical encoder designs risk sensor damage from vibration or shock, and some even use thin glass disks in “industrial” products. Our encoders use only unbreakable disks.

The HS6A offers a broad range of communication options, including parallel output, SSI, and the latest Profibus and Ethernet standards.

Our optical HS6A encoders use superior sensor, disk, bearing, and seal technology to deliver top performance in industrial conditions. Choose the HS6A encoder for reliable and durable performance in your applications.
