QM42 & QMT42 Series
Overview
- Features compact, low-cost dc sensors in NEMA 6 (IEC IP67) die-cast housings
- Delivers outstanding immunity to electrical noise
- QM42 series: Available in opposed, polarized retroreflective, diffuse, short-range adjustable-field and plastic fiber optic sensing modes
- QMT42 series (slightly larger): Available in diffuse, fixed-field and long-range adjustable-field sensing modes
- Offers the longest range—6 m—for any diffuse sensor on the market (QMT42)
- Includes marginal gain and Power ON indicator
