^1 The reference distance is the distance from the bottom edge of the head to the measurement centre of the Z-axis (height). See the Dimensions section for the installation reference plane. ^2 Do not view the beam directly using optical instruments (such as eye loupes, magnifiers, microscopes, telescopes, or binoculars). Observing the laser output using optical instruments is dangerous and may damage the eyes. ^3 Laser classification performed based on IEC60825-1 in accordance with FDA (CDRH) Laser Notice. ^4 The measured target is a KEYENCE standard target. Sigma value when the average height of 200 × 200 points in the centre of the field of view is measured using the height tool with reciprocating imaging OFF. ^5 The measured target is a KEYENCE standard target. Sigma value when the distance between two circles of 500 points in diameter set 1000 points apart at the centre of the field of view on a greyscale image is measured using the circle and circle distance tool with reciprocating imaging OFF. ^6 The measured target is a KEYENCE standard target. Value when the average height of 200 × 200 points is measured using the height tool with reciprocating imaging OFF. See the Dimensions section for the high-accuracy area reference plane. ^7 With YZ range minimum and Y thinning maximum. ^8 Laser ON input is enabled only when connected to a controller. ^9 The maximum value may be exceeded when extreme acceleration is applied. ^10 With an OP cable connected. ^11 When measuring white paper, illuminance on the sensor head receiving surface when light is applied to white paper. ^12 The head needs to be mounted to a metal plate to be used.
