01070-1265 is an incremental optical encoder from the HS35 series, designed for motor feedback, robotic control, and web process control applications. It features a rugged hollow shaft design with dual bearings and shaft seals, providing NEMA 4, 13, and IP65 environmental ratings when ordered with shaft seal or cable gland. The encoder operates within a temperature range of 0°C to 70°C (with extended temperature options available up to 105°C), and withstands shock up to 50 g's for 11 msec and vibration from 5 to 2000 Hz at 20 g's. The HS35 accommodates shafts up to 1" in diameter and offers a dual output option for redundant encoder signals or dual resolutions. Common applications include motor feedback and vector control, printing industries, robotic control, oil service industries, and web process control.
