The HL-T1 Sensor is an ultra-small laser Thru-Beam Sensor with very high resolution.
Three different types are available: HL-T1001F with a 1mm laser beam which is able to detect object 8µm in diameter at a distance of 500mm between receiver and transmitter; HL-T1005F and HL-T1010F with a laser collimator which produces a light curtain of 5mm or 10mm width respectively. The red Semiconductor LED, which belongs to Laser Class 1, makes it possible to use HL-T1 without any safety requirements
