The QR/P series offers a plug-in hybrid of both power and signal connections. The contacts at each end of the connector are spaced further apart to withstand a higher voltage, allowing for these positions to be used for power. The guide pins are made of steel to be robust enough to withstand accidental coupling shock. The receptacle housings are mounted to the board by self-adjusting floating bushings, providing a smoother coupling of the connectors. The crimp contacts are sexless and can be used in both plug and receptacle housings, allowing for higher utilizations and easier inventory control.
