Model DR21R | Replacement Encoder

DR21R The Accu-Coder DR21R is a highly customized, Direct Replacement Encoder with a unique, OEM specific ABS stepped voltage output channel.
DR21R configurations replace select Renco RCH20D and RHS25D models* originally installed on legacy F, H, W, N and HSM servo motor models.
An exact mechanical and electrical cross-reference for these obsolete Renco configurations, the DR21R also incorporates EPC's advanced Opto-ASIC sensing technology, providing superior thermal stability and signal reliability. The DR21R is available in 4 to 6 working days, with a Next Day Expedite option available, and it is fully backed by EPC's industry best 3-year warranty.

*These models have been discontinued by the manufacturer, and are increasingly difficult to find and costly to replace.
