4270-8Y is a circular connector – an accessory manufactured by Thomas & Betts for power and signal applications. It is designed for use in military, aerospace, computer, marine, communications and process control applications. The connector allows for rapid assembly on-site by providing a quick and easy connection of power and signal lines.

The 4270-8Y circular connector consists of two primary components - a contact receptacle (4271-8Y) and a contact plug (1212-8Y). The receptacle offers a maximum circular support of 8 positions and the plug offers the same. The receptacle and plug are both designed for quick assembly on-site. The receptacle and plug use spring-loaded type contacts, which are held in place by the housing, and offer reliable power and signal connections.

The 4270-8Y also offers high performance, with an impressive operating temperature ranging from -55°C to +125°C. It has a current rating of 35A (12.5A @ 300V) and an insulation resistance of 1000MΩ between adjacent contacts. The contact pin is rated up to 50A and the contact sleeve is rated up to 75A.

The 4270-8Y is designed with an IP67 rating, which provides protection from dust and water ingress. The connector also has a resilient ha6 housing material which enhances its resistance to corrosion and mechanical stress. Additionally, the circular connector is UL and CSA certified, and meets the relevant requirements in the respective certifications.

The working principle of the 4270-8Y circular connector is simple. When the contact plug is inserted into the receptacle, the contacts inside the receptacle engage with the contacts on the plug. This creates a secure connection and ensures the integrity of the connection. The contacts are spring-loaded, which allow them to easily engage and disengage without undue force.

In conclusion, the 4270-8Y circular connector is an ideal solution for power and signal applications. With its quick assembly, high performance and reliable connections, it is a great choice for military, aerospace, computer, marine, communications and process control applications. With its IP67 rating, robust housing and UL/CSA certification, it is designed to meet all safety standards and provide superior protection.
