Rectangular Connectors - Headers, Receptacles, Female Sockets

The M20-7870946 is a rectangular connector, specifically a header, designed for use primarily in industrial control panels or other industrial environments. It is built with durability and strength in mind, featuring a robust reverse-bayonet coupling design and a dual-layer contact system which provides reliable performance even in vibration-prone environments. The M20-7870946 connector is part of a range of high-performance, reliable rectangular connectors from TE Connectivity.

Application Field

The M20-7870946 is designed for automated industrial control systems and is rated up to 16A at 250VAC for power applications, making it suitable for use in outdoor industrial control equipment and various other industrial applications. It can be used for a variety of tasks such as for powering and controlling motors, connecting sensors and encrypting data transmission.

The M20-7870946 connector has been designed for easy installation in field-mounted applications and features quick connect and disconnect technology. It is resistant to corrosion and can be installed in harsh environmental conditions such as exposed to chemicals, dust, or dirt. It is also rated to an operating temperature range of -40°C to +105°C, making it ideal for outdoor applications in extreme conditions.

Working Principle

The M20-7870946 is made up of two main components: the header - an exposed socket - and the receptacle - an exposed pin. When connected, the header and receptacle form a secure contact point with a maximum current rating of 16A. The contact points are designed to ensure reliable signal and power transmission due to its dual-layer contact system.

The dual-layer contact system provides optimum contact resistance and ensures a reliable connection between the header and receptacle by creating an electrical connection between the two contact points. The current is then transferred along the conductor between the two contact points, and the electrical connection is reinforced by special ribs that lock into the housing, preventing the connection from loosening. This ensures a lasting, reliable connection even in vibration-prone environments.

The M20-7870946 has an integrated reverse-bayonet coupling system, which allows for easy installation in field-mounted applications. The reverse-bayonet coupling system allows the header to slide quickly into the receptacle and creates a secure locking mechanism to prevent the connection from loosening. This locking system ensures that the two contact points remain connected throughout the life of the device.
