Receptacle (ANSI C136.41-2013)

The mechanical and electrical interface between an outdoor luminaire and a photocell, typically mounted on top of the luminaire. The dimensions of the receptacle are roughly 1.5” high x 2.5” diameter. The 5-pin version has three line-voltage power contacts plus two dimming/signal contacts. The 7-pin version has three line-voltage power contacts plus four dimming/signal contacts. The 7-pin configuration supports field upgrades of the control capabilities of LED luminaires by adding or changing wirelessly networked controllers with sensing and communication abilities. The data interface protocol used by the dimming/signal contacts is not defined.
