OPKON Absolute Encoders: ERC10 BISS/SSI

Feedback encoder for synchronous gearless motors. BISS or SSI interface. Optical absolute encoder, 13 bit feedback data. Additional 1 Vpp (volts-point-to-point) Sin/Cos incremental signals. Physically compatible with SSI and EnDat layer. 10MHz clock frequency. Protected data transmission with CRC sum. IP 47 protection.

Description

The OPKON ERC10 BISS/SSI encoder provides precise absolute position feedback for servo motors using optical sensing. It features a rotating disk with transparent and opaque sections that modulate light, generating a digital signal corresponding to the shaft’s position. Supporting both BISS (Bidirectional Serial Synchronous) and SSI (Synchronous Serial Interface) communication protocols, the ERC10 ensures accurate and reliable data transmission. This encoder is ideal for applications requiring high resolution and consistent position tracking, even after power loss or system resets.
