RSF Elektronik Linear Encoder Readhead MS 20.74‑2 M
Compact optical readhead
Type: MS 20.74‑2 M Serial Number: 18 621 354‑01 Database Number: 555786‑04
Key Specifications - Supply Voltage: +5V DC - Signal Type: LD 5V (optical TTL) - Grating Pitch (Interval): 40µm – twice coarser than 20µm, offering a balance between resolution and speed - Reference Mark: RI‑Code 01 - Cable Code: G44 (specific cable/connector assembly) - Additional Code: F08 - Manufacturer RSF Elektronik (Austria)
Description This is a compact optical readhead designed for open-style linear encoders—mounts externally over a glass/metal scale (not included). The 40µm pitch offers medium resolution, suitable for applications requiring moderate precision with faster scanning capability. Its open design makes it ideal for clean, controlled environments—labs, assembly rigs, or light automation.
Typical Features & Benefits - Compact, lightweight construction - Moderate 40µm signal pitch (easily interpolated for finer control) - Reference mark support for positional reference - Differential TTL output ensures noise resistance - Ideal for tighter spaces or mid-resolution requirements
Applications - IC pick-and-place stages - XY/Z assemblies in inspection systems - Industrial measurement setups - Retrofit projects in leveling mechanisms - Test benches and repeatable-position tools
