The EDAC 337/387 Series Card Edge Connectors are designed for reliable interfacing with Printed Circuit Boards (PCBs). Featuring a 0.156" (3.96mm) contact spacing and 0.200" (5.08mm) row spacing, these connectors accept PCBs with a nominal thickness of 0.062" (1.57mm). They offer a high profile insulator body (0.600" / 15.24mm) and a card slot depth of 0.330" (8.38mm). The series supports single or dual row configurations, a variety of mounting options (flush or offset lugs), and accepts in-contact and between-contact polarizing keys. Pre-assembled card guides are also available. These connectors are RoHS Compliant and UL certified, making them suitable for a wide range of electronic applications.
