SR74 - Magnescale Incremental Linear Encoder 70-2040mm Measuring Length, IP54/IP65, 12±1×10-6/°C Thermal Expansion

SR74

SR74 is an incremental linear encoder from Magnescale designed for precise measurement with a range of 70 to 2040 mm measuring length.This encoder features a thermal expansion coefficient of 12 ±1 × 10-6/°C and offers selectable resolution options from 0.05 to 1 μm. It outputs A/B and reference point line driver signals compliant with EIA-422 standards. The SR74 is rated for IP54 protection without air purge and IP65 with air purge, ensuring durability in industrial environments. It operates within a temperature range of 0 to +50°C and withstands vibration up to 150 m/s2 and impact up to 350 m/s2. The unit requires a DC supply of +4.75 to +5.25 V with power consumption under 1.0 W.
