The 337/387 Series Card Edge Connectors are designed for reliable connections with a 0.156" (3.96mm) contact spacing. They offer a high profile insulator body for robust performance and accept standard P.C. boards of 0.062" (1.57mm) nominal thickness. These connectors provide a variety of contact termination options, including P.C. tail, wire hole, wire wrap, and specialized bends for extender boards and 90-degree applications. Available in single or dual row configurations, they support a wide range of mounting options such as flush or offset lugs, and can accommodate polarizing keys for accurate mating. Pre-assembled card guides are also available for enhanced usability. These connectors are RoHS Compliant and UL certified, making them suitable for various industrial and electronic applications.
