The 77311-402-20LF: The base product number is 77311; the -402-20LF suffix specifies the 20-position, tin-plated variant in a bag package.
No secondary lock or polarization keying is provided; the push-pull fastening relies on the receptacle's friction retention.
The 77311-402-20LF is sourced through independent distribution against your RFQ. Submit an RFQ for your BOM quantity to receive a firm quote.
The part number carries the LF suffix, indicating lead-free and RoHS-compliant plating.
Within the BERGSTIK® series, a 20-position unshrouded header with gold-plated contacts (e.g., 77311-402-10LF) offers higher mating cycle life for applications requiring frequent reconnection. The footprint and pitch are identical.
