Y17 series circular connector Y17-1604ZK10 male and female plug socket 4-core.
The Y17 series circular electrical connectors feature a bayonet coupling mechanism for quick and secure connection. Designed for high reliability, they are widely used in aerospace, electronic instruments, industrial control and other fields for circuit connection.Constructed with high-strength aluminum alloy shells and gold-plated copper alloy contacts, the connectors offer excellent mechanical performance and environmental adaptability, operating stably under temperatures ranging from -55 degrees to +125 degrees, high humidity and high altitude conditions.
With a five-keyway anti-mismating design, they ensure accurate and reliable mating.
