The 01002-10213 is a 2.5-inch solid shaft incremental encoder from BEI Sensors designed for industrial automation and motion control in ordinary and hazardous locations. This encoder features a square flange (D) housing configuration with shaft seal (SS) protection, delivering 2000 cycles per turn resolution with dual quadrature channels and index output (ABZ). The unit incorporates EMI shielding, high-precision ball bearings, and matched thermal coefficients on critical components to ensure reliable operation across a wide temperature range. With M18 connector termination and complementary outputs, the encoder meets IP66 sealing requirements and is available with certifications for intrinsically safe or non-incendive operation in hazardous areas, making it suitable for machine control, automation systems, and other demanding industrial environments requiring precise position feedback.
