They feature a compact, self-contained housing with a variety of mounting options enabling them to fit, or retrofit, most configurations. The sensors provide 20 to 140VAC or DC, or 20 to 270VAC or DC operation with a choice of P-MOSFET (sourcing) or N-MOSFET (sinking) solid-state output for enhanced sensor life and faster switching and response time than mechanical relays. Their LED status indicators are visible from 360 degrees for simple status monitoring from any angle.Banner Engineering Corp.www.bannerengineering.com888.373.6767
