Sullins – Dual-row HD board-to-board newcomers provide optimal connection integrity

Sep 1 2011 - Switches, Relays & Onboard [More Switches, Relays & Onboard Articles]

RoHS-compliant board-level interconnect specialist, Sullins Connector Solutions, has announced the addition of the dual-row 1mm centreline SBH51 Series of fully-shrouded male box headers and corresponding SFM210 Series fully-shrouded female header mates.

The parts are the newest members of the expanding SBH and SFM Series of fully-shrouded devices, and are engineered to minimize the risk of mis-mating in high-density board-to-board applications where superior signal performance is required. Provided in plated through hole (PTH), and with / without guideposts in surface-mount (SMT) terminations, they facilitate design flexibility and manufacturing efficiencies while helping to reduce vendor count. The UL94V-0 connectors feature an extended temperature range of -40C to +125C, and are compatible with reflow processes up to 260C peak.

Aimed at a wide range of high-density consumer, commercial and industrial applications where a PCB needs to be connected to another board, the 1mm pitch series is frequently specified for use on PCBs in household appliances, testing, computer, process control, security systems and telecommunications equipment. They are particularly appropriate for connecting boards in HVAC equipment, gasoline pumps, and vending machines.

These dual-row connectors are offered in 3 to 50 (6 to 100 pins) positions and have a current rating of 1A per contact. The SBH51 Series of headers may be ordered with either 10 microinch gold overall or gold flash overall plating; SFM210 Series of female mates are supplied with overall 10 microinch gold plating. Both series are provided with phosphor-bronze contacts. Insulator material is black liquid crystal polymer (LCP), and insulation resistance is 1000Mohm, says the company.
