Single Bearing 11mm Thickness Hollow Shaft 8-14mm Encoder P48
The P48 Incremental Optical Encoder (Hollow Shaft) features a unique through-shaft concentric locking device and single-bearing ultra-thin design, ideal for low-space installations. With an external diameter of 48mm, thickness as low as 11mm, and shaft diameter up to 14mm, it employs non-contact photoelectric principles for reliable performance. Equipped with reverse polarity and short-circuit protection, it offers multiple electrical interfaces and a resolution of up to 5000 PPR. Suitable for servo motors, robots, and automation control, it ensures precise positioning. Available with radial sockets (8P/14P) or a 1.0M radial cable, it weighs about 60g. Operating in -20°C to +85°C, it's designed for durability with die-cast aluminum construction. Perfect for high-precision industrial applications, it combines compact design with robust functionality.
