Sullins Connector Solutions has expanded its high-temperature portfolio to include a full series of double-row, dual edge connectors specifically engineered to facilitate board-to-board extensions, and to serve as board savers in board stacking and board extension applications without desoldering. The standard dual-row, 2.54 mm pitch connectors accept a 1.57 mm thick PC board in both slots and are offered with from 5 to 60 contacts per row. Optionally available are 3.18 mm and 3.96 mm contact center version with 5 to 40 pins per row.

Developed to deliver unsurpassed signal integrity, parts ensure PCBs are aligned at the centerline to enable a uniform signal path across the length of the connector. Sullins says the robust devices tested well with HTOL (High Temperature Operating Life), HAST (Highly Accelerated Stress Test), and LTOL (Low Temperature Operating Life). They are supplied in straddle-mount terminations, with flush mounting holes, or no mounting, to ensure optimal design flexibility.
Commonly employed in high-density, high-temperature, high-cycle life applications in which two 0.062-inch PCBs need be connected, the new dual edge connectors are billed as the ideal interface for R&D and life test applications. Devices may be specified in an array of industrial, consumer, and commercial systems and products, and are most commonly used in test and burn-in oven facilities, electronic component testing, data storage servers, communications and networking equipment, medical devices and LED applications.
The connectors feature a current rating of 3A per contact and a contact resistance of 30 milliohms maximum. Phosphor bronze contacts are provided standard with 30 microinch selective gold plating over 50 microinch nickel underplate. Parts can support an operating temperature of -65C to +125C or +150C, depending on the material configurations. While the +125C parts can withstand reflow processes up to 260C peak for 10 seconds, higher temperature parts can withstand as long as 120 seconds at 260C.
Housing materials are UL94-0 rated and insulation resistance is 5,000 megohm minimum. Devices further boast low insertion/withdrawal forces and a voltage rating of 750VAC minimum, says the company.
