Keyence LK-G155 Laser Displacement Sensor Head, Wide Type
Keyence’s LK-G155 is a laser triangulation measurement component. Keyence catalogs the LK-G155 as a sensor head. Spot and wide-beam heads behave differently on rough, curved, or reflective surfaces. Repeatability and linearity are the specifications that usually drive head selection. Applications range from electronics and battery inspection to machined component checks. Head-to-controller cables may be required and are ordered separately.
