KEYENCE LV-H62 Retro-Reflective Sensor Head, Spot Type Standard

The KEYENCE LV-H62 is a retro-reflective laser sensor head designed for precise long-distance detection. It uses a highly visible red laser beam (660 nm wavelength) to generate a small, concentrated spot, enabling detection of minute targets even at distances up to 7 m. The coaxial optical system eliminates detection point variations, achieving performance comparable to thru‑beam sensors. The housing is made of glass-reinforced plastic and weighs approximately 45 g, supporting stable operation in industrial environments. An integrated "Level Indicator" provides visual confirmation of detection stability, allowing users to check sensor status without referring to a separate amplifier display.

Applications:

• Detection of small components (e.g., electronic parts and protruding chips)

• Inspection of metal workpieces (e.g., detecting raised pins or the presence/absence of thin parts in automotive production)

• Positioning of partition plates or gaskets in narrow spaces

• General object detection in packaging, textile, and food processing industries

• The coaxial optical design aligns the light source and receiver to produce a straight beam, eliminating detection point variations for stable detection regardless of target position.

• The built‑in P.R.O. (Polarized Retro‑reflective Optics) function suppresses interference from reflective surfaces on the target, ensuring reliable detection.

• The visible red laser spot and Level Indicator simplify optical alignment and setup.
