1) Up to 15 expansion units can be connected.2) Sensing range with 8 ms response time. Reduction with shorter response time (see tables LL3/WLL180T).3) LL3-TX01.4) Objects to be sensed with 90% reflectivity (based on DIN 5033 white standard). Sensing range with 8 ms response time. Reduction with shorter response time (see tables LL3/WLL180T).5) LL3-DK06.6) See LL3 fiber-optic data.7) Average service life: 100,000 h at TU = +25 °C.MECHANICS/ELECTRONICSSupply voltage12 V DC ... 24 V DC 1)Ripple≤ 10 % 2)Power consumption50 mA 3)Switching outputPNPNumber of switching outputs2Switching modeLight/dark switchingSwitching mode selectorManually selectableOutput current Imax.≤ 100 mAResponse time≤ 16 µs, ≤ 70 µs, ≤ 250 µs, ≤ 2,000 µs, ≤ 8,000 µs 4)Switching frequency
