KRTW 3B/6.1321-S8 Contrast sensor

KRTW 3B/6.1321-S8
This contrast sensor features a teach input and time function, with an operating range of 14.5 mm ± 2 mm. It uses a white LED light source and offers a supply voltage of 10 to 30 V DC. Equipped with one digital switching output, it supports both light (PNP) and dark (NPN) switching. The device has a switching frequency of 10,000 Hz and connects via a 4-pin M8 connector. Its compact dimensions are 11 mm x 32 mm x 17 mm, housed in a plastic casing, with a teach button for operational control.
