Photo sensor T18-2VPFF50-Q8, fixed field 50 mm, PNP NO/NC, 10-30VDC, M12 4-pin, IP69K

T18-2VPFF50-Q8 is a Banner T18-2 series fixed-field photo sensor with a 50 mm cutoff and a visible red beam, in a right-angle 18 mm housing for washdown areas. It detects objects closer than the cutoff and ignores everything beyond it, so a background just behind the target does not switch the output.

• Sensing range: 50 mm cutoff, fixed
• Output: complementary PNP, Light Operate (black wire) and Dark Operate (white wire), 100 mA total (50 mA above +55 °C)
• Response: 2 ms ON, 2 ms OFF; repeatability 200 µs
• Supply: 10-30 V DC (10-24 V DC above +55 °C), < 16 mA
• Housing: right-angle, M18x1 thread, PBT polyester, PMMA window, epoxy-encapsulated electronics
• Environment: IP67, IP68, IP69K, -40...+70 °C
• Connection: integral M12 4-pin male connector

On dark targets the cutoff moves slightly closer: to 98 % of the nominal distance on an 18 % grey card and 95 % on a 6 % black card. There is no sensitivity adjustment. A green LED shows power and flashes at a marginal signal; the amber LED shows that the black-wire output is on.

ECOLAB certified chemical compatibility. Vibration tested to MIL-STD-202G, method 201A; shock to method 213B (75 g operating).
