Robust 3M 929975-01-03-RK boardmount socket with nickel underplating and tuning fork contact design
Product Overview
The 3M Boardmount Socket 929 Series offers a reliable interconnect solution for electronic applications. Featuring a .100" and .100" x .100" pitch with straight solder tails, these sockets are designed for single and double-row configurations ranging from 1 to 40 contacts (single row) and 2 to 80 contacts (two rows). The tuning fork contact design ensures robust connectivity, while solder standoffs facilitate efficient production wave soldering. An optional board retention feature is available for enhanced mechanical stability. These sockets are suitable for applications requiring a current rating of up to 2 amps and operate within a temperature range of -40C to +105C.
