The CCD-based SPR-02 single-point laser sensor uses optical triangulation measurement principles to deliver a resolution as fine as 0.001 in. (0.02 mm) at up to 1,800 measurement points per second. Available in a medium range Class IIIa and a long-range Class IIIb version, the unit has a measuring range varying from 32 to 168 in. (813 to 4,267 mm) and an offset distance from 6 to 16 in. (152 to 406 mm). Measurement sample rate is 1.8 kHz. The sensor operates in temperatures from 32 to 122F (0 to 50C), and power is provided by a 15-30 VDC power source.
