HENGSTLER Incremental Encoder
Model: 0 522 293
Type: RI58-O/500EK.42KB
1. General Description
The Hengstler 0 522 293 is a robust incremental encoder from the RI58-O series, which is a widely used industrial standard. It is designed to provide reliable speed and position feedback in a variety of automation applications, including machine tools, CNC axes, motors, and packaging machines.
This specific model features a 500 PPR resolution, a versatile Push-Pull (HTL) output with complementary signals, and a solid 10 mm shaft with a clamping flange. The “O” in the type code signifies it is the standard model with an aluminum housing.
Key Features 🎯
- Universal Industry Standard: Part of the 58 mm standard RI58 family.
- Solid Shaft Design: Features a 10 mm solid shaft with a clamping flange for secure mounting.
- Push-Pull Output: Provides a 10-30 VDC Push-Pull (HTL) output with complementary (inverted) signals (A, /A, B, /B, N, /N).
- Robust Housing: Durable aluminum housing suitable for industrial environments.
- Reliable Sensing: Uses a high-precision optical sensing method.
