HEIDENHAIN 383963-02 Length Gauge with Measuring Probe | ST 1278 M35-4E3B1Y-8192 Series
Engineering Background
HEIDENHAIN is a globally recognized German manufacturer of precision measurement and motion control systems, with over a century of engineering heritage. Their length gauges are the benchmark standard in dimensional metrology for machine tool verification, quality assurance labs, and high-precision manufacturing environments worldwide.
Product Positioning
The HEIDENHAIN 383963-02 is a high-resolution length gauge (ST 1278 series) equipped with a measuring probe, designed for non-contact or contact-based dimensional inspection in automated production lines and metrology stations. With an 8192-count resolution encoder (M35-4E3B1Y-8192) and E11100120 interface output, this unit integrates directly into CNC controllers, CMM systems, and industrial measurement networks requiring sub-micron repeatability.

System Architecture & Signal Flow
The 383963-02 length gauge operates as a closed-loop feedback element within a precision measurement chain:
- Probe contact → mechanical displacement detected by the ST 1278 gauge body
- Encoder conversion → M35-4E3B1Y-8192 encoder converts linear displacement to 8192-count incremental pulses
- Signal output → E11100120 interface transmits conditioned signals to the host controller or measurement display
- Controller processing → CNC/CMM system interprets position data for compensation, logging, or pass/fail decisions
This architecture ensures deterministic, low-latency measurement feedback suitable for real-time closed-loop control.
