OHSBCF Series Circular Connector Improves Connection Reliability with Bayonet Coupling and Metal Shielding

The performance of electrical connectors directly affects the stability and service life of electrical and electronic equipment. For equipment operating under wide temperature range, strong electromagnetic interference, vibration and shockprone environments, reliable contact performance, shielding property and secure coupling are critical factors.

The OHSBCF series small circular connectors adopt quick bayonet coupling structure. Different contact diameters deliver graded contact resistance: ≤10mΩ for φ0.6 mm contacts and ≤5mΩ for φ1 mm contacts, ensuring stable contact performance. These characteristics help maintain stable electrical connections, reduce signal interference, and support longterm service life during continuous equipment operation, even under demanding working conditions.

With interchangeability against OHS-BC series and partial RU ЕТ-СНЦ127 products, it acts as an alternative to RU ЕТ-СНЦ127. It supports multiple backshell options including straighttype and rightangle shielded backshells for plugs, and nutmounted receptacle versions. Pin and socket termination types cover solder termination and PCB termination according to customer requirements, offering high flexibility for different equipment and system integration.
