Banner Engineering Q20-2 Polarized Retroreflective Sensors
Banner Engineering Q20-2 Polarized Retroreflective Sensors offer excellent sensing performance with best-in-class optical-to-mechanical alignment for consistent lock and load mounting. These sensors feature a single-turn gain potentiometer, LO/DO switch, and bright indicator LEDs, providing easy alignment and configuration for reliable sensing. The Q20-2 photoelectric sensors are designed with standard 3mm threaded brass mounting holes on 1-inch spacing and help easy integration into tight spaces. These polarized retroreflective models for one-sided installation with a retroreflective target are ideal for detecting dark and shiny targets. The Q20-2 sensors come in compact, rugged, and sealed plastic housing.
