Smiths Interconnect’s Eclipta™ – ECL Series connectors have an innovative, double-ended edge-card contact system especially designed to deliver the reliability, serviceability, and affordability demanded by critical, disposable medical applications, including electrophysiology, mapping, and ablation catheters, home healthcare devices, and value medical systems. Since PCBs are often part of the disposable portion of medical devices, the Eclipta’s PCB also serves as the connector contact, which both eliminates the cost of the contact system on that side and further extends design flexibility by enabling the addition of embedded electronics, like EEPROMs, on either side of the board. The series also features a plug-and-play design that enables quick, effortless terminations and virtually eliminates potential contact damage, a unique connector shape and optional keying to ensure proper mating in fast-paced medical environments, a simple push-button active latch that provides audible mating confirmation and prevents inadvertent unmating, and fine-pitch, finger-proof contacts that contribute to both smaller footprints in medical equipment and the safety of patients and medical personnel. Eclipta connectors have plastic shells, are rated for temperatures extending from -40°C to +135°C and for up to 2,500 mating cycles to increase the mean time between failure (MTBF) on the reusable side, and tolerate standard sterilization protocols, including Autoclave, EtO, and Sterrad®. Additional benefits include scalability, high-density and custom designs, the ability to mass-terminate catheter wires directly to the PCB on both the disposable and reusable sides, and the ability to be reworked on the reusable side.
Materion’s high-performance iON connector materials offer engineered alternatives to electroplated contact surfaces in in safety- and cost-critical applications including disposable and limited-use medical connectors. Developed for use in harsh-environment applications, iON connector materials metallurgically clad contacts made of standard or custom composite alloys designed to deliver specific performance properties (such as enhanced resistance to extreme temperatures, vibration, and corrosion) directly into the connector material to reduce both the required amount and incurred cost of precious metal contact materials. Manufactured as inlay-clad stripes in copper spring alloys, iON connectors have fully dense structures with limited porosity, which achieves improved wear performance and contact integrity compared to electroplated contact surfaces and supports high-reliability performance in extreme environments. They also offer overall contact layer thicknesses down to 0.5µm, which allows them to function as drop-in replacements for electroplated gold and palladium contacts, and are available in three standard contact finishes. The first, iON – GR, is a composite alloy of silver and palladium with a noble-gold-enriched contact surface that offers low-cost replacements for connectors electroplated with hard gold, as well as improved stability in high-temperature and high-vibration applications. The second, iON – HW, has an ultra-hard wrought nickel/palladium base layer with a gold-enriched surface and offers maximum wear performance in high-vibration applications with sliding or make/break contacts. The third, iON – HT, is a stable silver/palladium/gold alloy that provides high hardness, nobility, and supreme temperature stability ideal for use in applications with operating temperatures as high as 350°C. Custom solutions are also available. disposable and limited-use medical
