Compact device size is an overwhelming trend in modern electronics, but connectors for compact medical devices must be safe, easy to terminate, and widely configurable, in addition to small in size and extremely reliable.

Innovations are critical in the medical field, and new devices are showing up on the market every day. It has been estimated that medical device makers spend up to 7% of their revenue on research and development, which is a much higher percentage than other industries. New wearable devices, such as glucose monitors and fitness monitors, are entering the market at a fast pace. Additionally, demand is rising for minimally invasive surgical procedures, which is driving the need for new handheld devices. Of course, in the medical field, safety is a primary concern. Connectors used in medical devices must be easy to terminate, as well as safe and reliable in the field.

As with almost any design, the more options a connector manufacturer can provide for an engineer, the more flexible an engineer can be in their design. Since medical device designs are actively responding to market demands for smaller physical dimensions, smaller-sized connectors are widely needed. Products with a centerline spacing of 2.5mm provide a good compromise between size and flexibility in medical designs, can be obtained in one to eight positions, and, with UL-rated currents up to 5A at 150V, can easily power handheld devices used for surgical procedures. These types of conn
