The female vertical connectors are available in through-board and SMT designs in pin counts of 6, 10, 12, 16, 20, 26, 34, and 50 contacts. The captive screws with hex socket heads prevent slipping during assembly. The design of these captive screws allows for ‘Mate before Lock’, meaning connectors can be fully mated before the screws need to be engaged. This provides for faster and easier assembly. Reverse fix options are also available, allowing board mount screws to fasten to the PCB.
