Luminescence sensors – BLT0009
The BLT 21M-001-P-S4 luminescence sensor, order code BLT0009, belongs to the 21M series and has dimensions of 12 × 50 × 42.5 mm. Its interface is PNP with NO/NC switching. The input functions comprise key disable on/off and Teach Contrast (switching point). The sensor operates according to the luminescence sensor principle and uses focused diffuse sensing with coaxial optics. Its beam characteristic is focused, and it uses ultraviolet light. The light spot size is Ø 1.5 mm at 10 mm. The operating range is 0...40 mm.
The sensor has a 4-pin M12x1 male connector. Its housing consists of powder-coated zinc die casting and aluminium; the sensing surface is made of glass. The operating voltage is 10...30 VDC. Approvals and conformity markings are cULus, CE, UKCA and WEEE.
