MicroBridge® Automotive Connectors

TE Connectivity's (TE) ERNI Connectors MicroBridge® Automotive Connectors are built to meet the exacting demands of the modern automotive industry. These single-row, 1.27mm-pitch wire-to-board connectors deliver up to 9A per contact at +20°C. With its robust and rugged design, the miniaturized series features SMT and IDC termination styles, 2- to 20-pin counts, as well as dual latching and integrated strain relief. The electrical connector position assurance (CPA) option provides connectivity assurance through the use of a shortened pin that has no signal or current transfer function. ERNI MicroBridge Automotive Connectors have coding/color options and operate in a temperature range from -40°C to +150°C. All of these features benefit any application that has extreme temperatures, space constraints, or a rugged environment.
