ENCODER – COA34-01
Brand : Codechamp
The COA34-01 is a single-turn absolute optical encoder with a hollow shaft, designed for industrial applications requiring extreme angular precision and simplified mechanical integration.
With a resolution of up to 25 bits and an accuracy of ±5″, it ensures reliable and stable measurement over a full rotation, even in demanding environmental conditions.
The COA34-01 converts mechanical rotation into an absolute digital signal with outstanding reading accuracy.
Its SSI2 / SSI serial interface and compatibility with +5 V and +15 V power supplies ensure easy integration into a wide range of control and servo systems.
Thanks to its hollow shaft design, it allows direct mounting on motor shafts or through-shaft assemblies, reducing space requirements and improving installation reliability.
Note: Ideal for applications requiring high precision and compactness, the COA34-01 combines performance and durability.
