Circular Connectors - Contacts

21-033471-001 application field and working principle

Circular connectors are electrical connectors that connect two or more electrical circuits. Known as circular multi-pin electrical connectors, they typically have a round shape or cylindrical structure, allowing them to be connected easily in a variety of applications. The contacts of the circular connector can be adapted according to the needs of the application, with different numbers and types of contacts being available. Connectors can range from small-format connector sizes, such as 0.3 mm pitches, to larger formats such as 7/16” pitch, as well as a variety of voltage ratings.

21-033471-001 is a type of circular connector contact, with the following features:
• Contact: receptacle
• Total circumference of contact: 2.5 mm
• Insulation O.D: 1.95 mm
• Rated current per contact: 0.45 A
• Contact material: brass
• Number of contacts: 4-pin
• Type of mating: Crimp

21-033471-001 is suitable for a variety of applications, both commercial and industrial. It is particularly suitable for use in the following environments:
• Electrical and electronic equipment
• Automotive applications
• Telecommunications and data communications equipment
• Medical devices
• HVAC systems

The working principle of 21-033471-001 is based on a removable receptacle and contacts that offer a secure, reliable connection. The contacts are crimped onto the receptacle, making a physical and electrical connection. The contact is held in place by the force of the crimp, while the insulation provides a barrier against water and other contaminants. The contact material is made of brass, making it highly conductive and resistant to corrosion and wear.

21-033471-001 is designed to provide a reliable connection with a small footprint. It is quick and easy to install, and is suitable for a wide range of applications. The contacts can support up to 0.45A per contact, making it suitable for low voltage and current applications. It is also designed to offer excellent EMI/RFI protection, making it suitable for applications where electrical interference is a concern.
