October 7, 2009 -- Engineers seeking to leverage Souriau's lightweight, high-density microComp connector line in harsh environment applications can now take even more weight off their designs without compromising hermetic integrity, with an aluminum compatible microComp hermetic receptacle now available from U.S. subsidiary company PA&E (Wenatchee, WA).
Souriau's microComp connector line is suited to applications that require a lightweight, high-density rectangular connector. The microComp connectors typically weigh 60% less and are 25% smaller than standard high-density Sub-D connectors, claims the company. The parts can be built with as few as seven or as many as 104 contacts and have a contact pitch of 2.0 x 1.7 mm sq. The microComp line comes in both space and military grade configurations; each connector offers dismountable contact construction for wiring flexibility.
According to the company, the aluminum compatible PA&E microComp hermetic receptacle is currently designed for the microComp 25-pin configuration and offers a weight savings of up to 40% when compared to stainless steel alternatives. It has a leak rate of less than 1X10-9 cc/sec helium at one atmospheric differential pressure thanks to PA&E's Kryoflex polycrystalline ceramic. Kryoflex-sealed connectors may provide superior electrical performance -- up to 70 times the current-carrying capacity of conventional products -- while withstanding extreme mechanical and thermal stresses.
The microComp hermetic receptacle provides an insulation resistance of greater than 5,000 megohms at 500 VDC when tested in IAW MIL-STD 1344, Method 3003. It is built with beryllium copper alloy contacts that are finished in nickel/gold and has an operating temperature range of -55°C +170°C. The microComp receptacle is designed for aluminum, titanium or iron/nickel alloy applications and is available in laser-weldable or o-ring mount styles. These receptacle connectors are also available in a double-ended bulkhead configuration for applications requiring an interconnection on both sides.
