[FAQ] Technical Absolute FAQs Sourcing Guide

Explore standard queries regarding the EPOCH RZ35 absolute absolute Multi-turn Encoder series to secure proper cross-references:

[Q:] How does the EPOCH RZ35 function as a compatible cross-reference for a Tamagawa SA35 absolute encoder?
The EPOCH RZ35 absolute encoder is designed to serve as a mechanically and electrically compatible alternative for the Tamagawa SA35 (TS5667/TS5668 series). It matches the 35mm outer diameter and offers customized mounting pitches (PCD d31 or d40) alongside hollow shaft (6mm/8mm) or 9mm conical shaft alignments, running the same 2.5MHz RS485 serial data format.
[Q:] What battery voltage specification is required for the RZ35 multi-turn memory retention?
The RZ35 multi-turn memory is backed up by an external battery supply line. The backup range is standard 3.0V to 3.6V (typically 3.6V DC). The encoder features intelligent battery health indicators: it triggers a low battery warning at 3.1V and reports a position tracking fault if the backup drops below 2.5V.
[Q:] What serial communications interfaces are supported by the RZ35 series?
Our RZ35 series absolute encoders standardly support high-speed RS485 serial communication with a 2.5MHz baud rate (Tamagawa protocol compatible). It can also be manufactured with alternative industry interfaces such as SSI or BiSS protocols to drive dynamic closed-loops on diverse CNC systems.
