01070-294 is an incremental optical encoder from the HS35 series, designed for rugged industrial environments requiring reliable position feedback. It features a hollow shaft design accommodating shafts up to 1" in diameter, with dual bearings and shaft seals providing NEMA 4, 13 and IP65 environmental protection. The encoder operates within a temperature range of 0°C to 70°C (with extended options available up to 105°C), withstands shock up to 50 g's for 11 msec and vibration from 5 to 2000 Hz at 20 g's. With humidity tolerance up to 98% RH without condensation and available disc resolutions up to 80,000 counts, this encoder is well-suited for motor feedback, vector control, robotic control, printing industries, and web process control applications.
