Model	LK-H028
Mounting mode	Diffuse reflective
Reference distance	20mm
Measuring range	±3 mm*1
Light source	Type	Red semiconductor laser
Wavelength	690nm
Laser class	Class 3B
Output	50mW
Spot diameter (at standard distance)	25 µm x 1,400 µm
Linearity	±0.02% of F.S. (F.S. = 6 mm)*2
Repeatability	0.02 µm (0.01 µm)*3
Sampling cycle	2.55, 5, 10, 20, 50, 100, 200, 500, 1,000 µs (selectable from 9 levels)
Temperature characteristics	0.01% of F.S./°C (F.S. = 6 mm)
Environmental resistance	Enclosure rating	IP67
Ambient light	Incandescent lamp or fluorescent lamp: 10,000 lux or less
Ambient temperature	0 to +45 °C*4
Relative humidity	35 to 85 % RH (No condensation)
Vibration resistance	10 to 55 Hz, Double amplitude 1.5 mm, 2 hours in each of the X, Y, and Z directions

1 For details on the measurement range, see page 1 - 12 (when the sampling cycle is between 2.55 and 10 µs). 2 This value was taken when measuring a KEYENCE standard target (white diffuse object) in standard mode. 3 These values were taken when measuring a KEYENCE standard target (white diffuse object) at a reference distance and with the number of averaging measurements set to 16, 384. The value in the parentheses is a typical e x ample when measured with 65, 536 averaging measurements. 4 If the ambient usage temperature is 40 °C or higher, the LK-H023/H028 must be used while attached to a metal plate.
