Sullins announces RDPS card edge connectors

RDPS devices are engineered to accept 0.062in (1.58mm) thick daughtercards and the range is comprised of 0.100in (2.54mm), 0.125in (3.18mm) and 0.156in (3.96mm) contact centreline parts.

The double-contact-point pin design promotes sturdier daughtercard retention than traditional card edge connectors.

This pin design, coupled with the series material rating of -65C to +150C, helps ensure high mating cycles, and long life for electronic systems and end products.

The series also offers design flexibility as devices are supplied in dip solder, wire wrap, right-angle bend, and card extender terminations, as well as with a choice of post lengths.

Available mounting styles include clearance holes, threaded inserts, side mounting and with/without mounting ears.

Materials are UL94V-0 rated.

RDPS devices may be specified to connect high-density PC boards to 0.062in daughtercards in a wide range of industrial, consumer and commercial systems, plus end products that need be resistant to vibration, drop shock and short-circuits involving printed tracks on the PC board.

Due to their durable double-contact-point pin construction and high-temperature rating, the connectors are suitable for use in test and burn-in oven facilities, power converters, power suppliers, electronic component testing, communications equipment, medical equipment and automotive applications.

The double-row parts feature a current rating of 3A per contact, and are provided in 6-70 contact positions (12-140 pins).

Rated to withstand +150C continual heat, the processing temperature range is up to 260C peak for 120 seconds.

Insulator material options are PBT, PA9T or PPS.

Connectors are supplied as standard with 10 micro inch or 30 micro inch selective gold-plated phosphor bronze or BeCu (beryllium-copper) contacts to facilitate high-reliability soldering.

They also feature a fully-insulated 50 micro inch nickel underplate.

Additional specifications include an insulation resistance of 5,000 megohms minimum at 125V DC, and a 16-ounce maximum insertion force and a 1-ounce minimum withdrawal force per contact pair.

Contact resistance is 30 milliohm maximum.

Parts rated to +175C, and those requiring customisation, may be specially ordered.

The company also offers complete specifications regarding operating, processing, temperature and material options for the RDPS connectors.
