Photoelectric rotation detector
LG-930

The LG-930 is a non-contact rotation detector that uses red visible light as a light source and detects reflected light. It is typically used with a reflective mark (sold separately) attached to the rotation axis. It is compact, measuring 76.5 mm in length, and can detect objects from a maximum distance of 200 mm.

Features

  • The integrated structure of the light emitter, light receiver, and amplifier provides both functionality and high precision. Furthermore, it boasts a lightweight and compact design.

  • LEDs are used as the light-emitting element. This eliminates the wire breakage that often occurs in lamps.

  • Because it is a non-contact detection method, it does not place any load on the object being measured.

  • High performance that allows for a maximum distance of 200 mm from the object being measured.

  • Because it's compact, it doesn't require much space for installation. It also comes with an L-shaped bracket for easy mounting.

  • It uses visible light for easy alignment and also has a built-in operation indicator light, making setup simple.

  • The light source uses a pulsed lighting method, making it resistant to the effects of ambient light.
