Model DR21R Description
The Accu-Coder® Model DR21R is a highly customized, Direct Replacement Encoder with a unique, OEM-specific ABS stepped voltage output channel. Model 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.
*These models have been discontinued by the manufacturer, and are increasingly difficult to find and costly to replace.
