01102-022 is an incremental optical encoder from the HS35 series, designed for motor feedback and industrial control applications. This hollow shaft encoder features a rugged metal housing with dual bearings and shaft seals, providing NEMA 4, 13 and IP65 environmental ratings. It 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. The encoder accommodates shaft bores up to 1.00" in diameter and offers dual output options for redundant signals or dual resolutions. Common applications include motor feedback and vector control, printing industries, robotic control, oil service industries, and web process control.
