K38 Small economic univeral high pulse encoder up to 50 to 32768ppr
The K38 Incremental Optical Encoder (Blind/Through Shaft) offers a compact, economic design for industrial automation. With an external diameter of 38mm, thickness 38mm, and shaft diameter up to 8mm, it features a ring locking structure and non-contact photoelectric principle. Equipped with reverse polarity and short-circuit protection, it supports multiple electrical interfaces (OC, Push-pull, TTL/HTL) and delivers resolutions up to 32768 PPR. Suitable for textile, packaging, motors, elevators, and CNC systems, it ensures precise positioning. Choose between radial/axial cables (1M standard) with IP50/IP65 protection. Weighing 140g, it operates at ≤6000 rpm (IP50)/≤4000 rpm (IP65) in -20°C to +90°C, ideal for harsh environments.
