MICRODOT Microminiature D Connectors Featuring DEUTSCH 1-1532201-2 for Computers Test Equipment and Aerospace
MICRODOT Microminiature D Connectors
The MICRODOT Connectors MCK and MCD series offer a complete connector system adaptable to various form factors. They feature low engaging force achieved through a unique twist pin contact design, ensuring electrical contact at multiple points around the pin periphery. These connectors are designed to meet applicable requirements of MIL-DTL-83513 for intermateability, interchangeability, and performance. Ideal for miniaturized airborne and space electronics, computers, and test equipment, the MCK series has metal shells and the MCD series has plastic shells. Both are available with solder cup, and solid or stranded wire terminations. MCK transition blocks are standard for printed circuit board mounting. Custom termination configurations and wired harness assemblies are also available.
