Y2 Series Circular Connectors

The Y2 series circular connector is an upgraded version from the obsolete plug connector or simply the P type. Built to Q/321283LSC02-2007 specifications, this electrical connector is the fundamental building block of integrated electronic systems, where it is used to provide electrical connection and transmit signal between devices, assemblies, and systems.


Unique bayonet coupling is selected for ease of engagement and disengagement. Available in a variety of specifications, this Y2 series circular connector features a socket that is tightly sealed to prevent water ingress. The plug connector is typically mounted in one of two ways, via flange or power cable. Here are a few of many benefits associated with the use of KAIDA electrical connector:
1. Small size, light weight, and ease of use
2. Able to withstand repeat handling (mating and unmating)
3. Excellent electrical conductivity
4. Airtight, waterproof seal
5. Contact retention: 0.2Mpa

Y2 Series Circular Connectors

The connector shell is an aluminum alloy casting. Available with corrosion and wear protection plating and coating, the Y2 series connector works properly at an altitude of 20000m and a temperature range between -55°C and -125°C. Typical applications for this connector are in the weaponry and electronic systems.
