Circular connectors are widely used in many technical fields, from medical equipment to aerospace, to ensure reliable connection of power and signal cables. In this article we will focus on 27913-08T9 circular connectors. We will discuss their application field and working principle.

27913-08T9 circular connectors, also known as mini four contact, are robust and feature high-temperature tolerance and vibration resistance, making them a popular choice in a variety of industries. The operating temperature range of these connectors is from -55 up to 125°C, and the electrical insulation has an impressively high voltage rating of 600V AC and 250V DC. They are normally available with pin or socket contacts in Polarized, Keyed, Receptacle, or Plug configurations.

This kind of connectors is often used in applications that require space-saving components and harsh environment conditions, such as in the automotive industry. They are also highly suitable for use in medical and industrial equipment, because they can endure vibration and are resistant to many solvents and chemicals. With amazing tensile strength and resistance to impacts, they make an ideal choice for many aircraft applications, too.

These connectors have a contact layout with four contacts in a 360-degree configuration. The mating design provides both physical and visual keying to prevent wrong connection and to help reduce expensive mis-assembly. This is ensured by the use of a multi-flux contact design. The connectors also feature a reliable bayonet-style locking system, which also adds to their robustness and ensures a secure connection.

The 27913-08T9 connectors have an operating force of approximately 2.5 lbf (11.4 N). Their total contact resistance is low - 20 mΩ max initial - and their insulation resistance is high (it is >5 MΩ for connector-to-connector). The connectors can also manage steady-state currents up to 12 Amps.

These impressive features make the 27913-08T9 circular connectors a versatile and reliable choice. They are lightweight, compact, and vibration-resistant, making them suitable for many demanding applications. Furthermore, the bayonet mating feature, keyway, and multi-flux contacts add to their robustness and ensure reliable and secure connection.
