Banner SME312LPCQD Photoelectric Sensor | 1m Polarized Retroreflective, NPN/PNP, M18
Banner SME312LPCQD Mini-Beam Expert series sensor. 1m range, polarized retroreflective, 10-30V DC, dual NPN/PNP output, M18 threaded barrel, IP67.
Product Overview
The Banner SME312LPCQD is a compact M18 miniature photoelectric sensor from the Mini-Beam Expert series. It features polarized retroreflective sensing technology with a 1-meter range, designed for reliable detection of reflective objects while ignoring glare. The sensor operates on 10-30V DC and provides both NPN and PNP outputs (bipolar) via a 5-pin M12 quick-disconnect connector. Its IP67-rated thermoplastic housing and threaded barrel design make it suitable for space-constrained industrial automation applications.
