Electrical connectors

Size 12 contacts capable of supporting 40 amperes per contact have just been added to this company's line of Power Connection System products. The contacts have a large surface area mating system, and are said to be hot pluggable to 25A per contact at 250V ac. The male contacts are shrouded for safety against contact with high voltage when the connector system is disconnected.

PCB headers

Surface-mountable PCB headers from this company are said to improve solder joint strength in a wide range of PCB applications through enhanced capillary action of reflowing solder. The capillary action of the reflowing paste is said to draw the header down tightly to the PCB, creating a thinner and stronger solder-joint, with a reported 50% higher retention force than other designs.
