The closed-end feature prevents the IDC contacts from being pushed through the housing during assembly, a common issue with open-ended designs. Tin plating on the female socket means this connector is built for cost-sensitive, moderate-cycle applications rather than high-reliability field-service duty.
Wire Gauge and Termination — What 32 AWG IDC Means
This connector terminates 32 AWG discrete wire via insulation displacement.
Position Count and Series Siblings
The SUR series includes 4-position (04SUR-32S), 6-position (06SUR-32S), and 10-position (10SUR-32S) siblings at the same 0.031" (0.80 mm) pitch and with the same IDC termination for 32 AWG wire. If your design needs a different circuit count, the same tooling and wire specification apply across the family.
