The LG-930 is engineered for precision speed detection using photoelectric principles. A small reflective target affixed to a rotating component allows the detector to sense each revolution without contact, preserving the test object’s integrity. The pulse-light source effectively reduces interference from external light, maintaining consistent measurement, even in challenging environments. Ideal for labs, workshops, and industrial testing, the LG-930 blends reliability, portability, and clarity in one easy-to-use module.

  • Built-In Optical and Electronic Components – Integrated light projector, receiver, amplifier, and signal shaper in a compact body for simplified operation.

  • Reflective Non-Contact Detection – Measures rotation using a reflective mark placed on the target object; no mechanical contact needed.

  • Pulse Lighting Technique – Minimizes interference from ambient light, enhancing detection accuracy.

  • Medium Detection Range – Effective sensing distance from approximately 70 mm to 200 mm.

  • Fast Response Speed – Handles rapidly rotating targets accurately, with detection capacities around 25 meters per second.

  • Simple TTL Output – Provides a clean digital signal compatible with tachometers, data loggers, and analyzers.

  • Compact and Lightweight – Easy to install and position in tight or mobile setups, with minimal footprint.
