The OptoPulse EIL580 family of 58-mm optical incremental encoders is available from Baumer (Southington, CT). Available in various mechanical designs, the family includes clamping flange encoders with 10-mm solid shafts, synchro flange encoders with 6-mm solid shafts, and 8- to 15-mm blind hollow shaft and through hollow shaft models. All encoders feature graduated disc increments that can provide 100 to 5,000 impulses per turn.
Designed for high-precision applications, the optical sensing capability enables signal quality in temperatures from -40 °C to +85 °C. The encoders feature solid die-cast housings with 1.5-mm aluminum walls, short-circuit-proof connections to guard against reverse polarity, and optional IP 67 protection. The ShaftLock feature protects the bearing pack from misalignment and prevents the code disc from damage caused by excessive shaft load. Shock protection to 300 g and vibration protection to 30 g are provided.
