HOLLOW SHAFT ABSOLUTE OPTICAL ENCODER COA40-01 – 25 BITS

Brand : Codechamp

The COA40-01 is a single-turn absolute optical encoder with a hollow shaft, designed for industrial applications requiring high-precision position measurement and simplified mechanical integration.

With a resolution of up to 25 bits and an accuracy of ±5″, it ensures reliable, stable and repeatable motion readings, even in the most demanding environments.

The COA40-01 provides absolute measurement over 360°, with no loss of reference at power-up.

Its optical technology delivers exceptional signal stability, while its SSI2 / SSI serial interface ensures fast and secure data transmission.

Thanks to its hollow shaft design, it integrates easily into complex mechanical assemblies (motor shafts, actuators, through-shaft systems), reducing space requirements and simplifying installation.

Note: This model combines high angular precision, mechanical robustness and ease of integration, making it a preferred choice for industrial automation.
