Circular Connectors
Circular Connectors refers to electrical connectors with a circular mating housing and a defined contact insert. Contacts, insulation, mating geometry and shielding establish the installed electrical channel, with reliability depending on the whole connection.
Product & engineering
Understand the product.
Circular Connector applies to any electrical connector possessing multipin interconnects with cylindrical contact housings and circular contact interface geometries. Circular connectors are selected for ease of engagement and disengagement, their ability to conveniently house different types of contacts, their wide range of allowable contact voltages and currents, their ease of environmental sealing and their rugged mechanical performance. The primary disadvantage of the circular design is loss of panel space when used in arrays when compared to rectangular connectors.
Circular connectors are prized because of their durability. Many circular connectors have either threaded components on the ends or lock in other ways that prevent them from being forcibly pulled out of their socket when they are connected. This makes them ideal solutions for situations where force may be applied to the cable that they terminate or where the environment may be one where it's likely that some sort of contaminant could be introduced into an open connection.
For this subject, the supplied object is electrical connectors with a circular mating housing and a defined contact insert. Evaluate the mated pair with cable or board launch, contact load, alignment and environment. Current heating and high-speed signal integrity are separate limits. Floating or hermetic designs solve particular mechanical or sealing constraints; they do not remove the need to verify pin assignment, insertion cycles, shielding and the full mating system.
What turns activity into demand
Qualified circuit architectures define contact count, mating geometry and current or signal duty. Production volume, rework and replacement turn those designs into connector shipments.
The commercial boundary
A connector pair, contact, housing and cable assembly are distinct procurement objects. Speed, power and industry classifications overlap and must be reconciled before totals are combined.
Why can a compliant connector fail in the installed channel?
