J30J Metal-Shell Micro-D Connectors
1.27 mm pitch · 5 to 144 contacts · twist-pin contacts
J30J Mixed-Power Micro-D Connectors, 20 A Power + 3 A Signal
20 A power + 3 A signal · micro-D size · twist-pin signal contacts
J30J mixed-power connectors carry 20 A power contacts and 3 A signal contacts in a shell similar in size to a standard J30J micro-D. Signal contacts are gold-plated twist pins with multiple contact points, so power and signal share one compact, vibration-resistant connector.

Frequently asked questions
Why use a mixed-power micro-D?
It puts power (20 A) and signal (3 A) through one small connector instead of two, saving panel space and weight.
Can you make other power and signal combinations?
Yes. Tell us how many power and signal circuits you need and we will propose a layout.
