Connection options: A model with a QD requires a mating cordset (see page 299).

For 9 m cable, add suffix W/30 to the 2 m model number (example, LT3BD W/30).

†

Retroreflective range is specified using a BRT-TVHG-8X10P high-grade target.

Actual sensing range may differ, depending on the efficiency and reflective area of the retroreflector used. See Accessories for more information.
