Product Description

The Mitsubishi Q172EX-S2 is a motion encoder interface module designed for the MELSEC-Q Series programmable logic controllers (PLCs). It facilitates the connection of serial absolute synchronous encoders, such as the Q170ENC, to the Q173H or Q172H motion controllers. This module supports a maximum of two encoders per unit and provides two tracking input points, enabling precise position feedback in high-speed motion control applications. The Q172EX-S2 is ideal for systems requiring accurate synchronization and real-time data acquisition from multiple axes.​
