Product OverviewPositronic's Combo-D series connectors offer a versatile solution
for mixed-contact applications, allowing combinations of power,
shielded, air, high voltage, and signal contacts within a single
connector body. Available in standard and high-density
configurations across six shell sizes, these connectors are
designed for professional, industrial, and military quality
applications, providing three performance levels for optimal
cost-performance ratios. They are suitable for sheltered,
non-corrosive indoor and outdoor environments with normal
ventilation. Options include various contact termination types,
mounting styles, and locking systems to meet diverse application
needs. Product Attributes- Brand: Positronic
