The DR738 is a rugged incremental rotary encoder designed as a direct replacement for 444 Tach style encoders, featuring a 115 mm diameter flange and precision ABEC ball bearings. It supports shaft sizes of 11 mm or 12 mm with keyways, operates from 0° to 70° C (or 0° to 100° C for high temperature variants), and delivers up to 30,000 CPR with output frequencies up to 1 MHz. Output types include open collector, pull-up, push-pull, and line driver formats, with IP64 sealing available. The encoder meets electrical noise immunity standards BS EN61000-4-2, IEC801-3, BS EN61000-4-4, DDENV 50141, DDENV 50204, BS EN55022, BS EN61000-6-2, and BS EN50081-2. Max shaft speed is 6000 RPM, with radial and axial shaft load ratings of 27 lb each. Mounting is compliant with 444 Tach style, and connector options include 6-pin, 7-pin, 10-pin MS, 5-pin or 8-pin M12, and 9-pin D-subminiature.
The DR738 provides a digital encoder signal format to replace traditional Tacho style feedback devices. The heavy duty bearings and mechanical assembly make the DR738 perfect for those applications requiring a rugged and dependable encoder. Typically replaces encoders from Hubner, Baumer, Tekel, and others.
