ITT's Miniature Filter Spring Probe & Pad Contact Technology Extends Operating Life

Advanced 24-spring probe & pad contact technology qualified to more than 10,000 mating/unmating cycles.

Santa Ana, CA, December 10, 2011 --( ITT Interconnect Solutions, a leading global manufacturer and supplier of connectors, interconnects and cable assemblies, has developed a miniature filtered interconnect that offers more than twenty times the service life of other filter connectors on the market. Featuring an advanced 24-spring probe & pad contact technology, the Filter Spring Probe Series connector is qualified to more than 10,000 mating/unmating cycles, a significant increase compared to the previously accepted benchmark of 500 cycles for conventional pin socket contacts. Available in a much smaller package than conventional circular connectors, e.g. 38999, the Filter Spring Probe Series connector is designed to extend the operating life of in-the-field military equipment, drastically reducing operational costs.

The new filter spring probe & pad contact technology creates electrical contact by utilizing pressure-point force of the spring-loaded pin to the contact pad, instead of the sliding forces typically found on conventional pin socket contacts. The contact pad on the receptacle (device) side of the connector is flush with the mating face of the connector and can be easily cleaned by simply wiping the interface. This is an extremely attractive feature for field applications where dirt, moisture, mud, sand and other contaminants may be present. The ultra-small, 24-contact design delivers the desired miniaturization and high-density configurations to provide a low-weight, high-performance product.

"The Filter Spring Probe Series connector devices provide a robust and durable interconnect solution designed to deliver a long lifecycle in harsh environments," Dom Lecce, product manager at ITT. "With the 24-spring probe & pad contact technology, we have developed one of the most reliable, longest-lasting military connectors available on the market."

The Filter Spring Probe Series connector is suitable for applications including military radios, surveillance systems, night vision goggles, soldier combat systems, IED countermeasures, head-up displays, detection equipment and radar systems.
