Rectangular Connectors - Headers, Receptacles, Female Sockets

SFMC-139-L1-SM-D is a header type rectangular connector, primarily designed for board-to-board interconnections. The rectangular form factor provides a simpler, more reliable interconnection solution for applications requiring off-board connectors. The horizontal, or right angle, orientation provides a high density, robust, and secure connection.

SFMC-139-L1-SM-D connectors are designed for applications where power transferring and signal/data transferring occurs in the same connector. This type of connector is also suitable for applications where ease of assembly and rigid hold onto the mating part/PC board are important factors. The SFMC-139-L1-SM-D header type rectangular connectors also feature a well-designed “lock-in” mechanism that helps to ensure continuity between connectors at connection and prevents accidental disconnection.

Features of SFMC-139-L1-SM-D Connectors

• Compatible with commonly used mating interface dimensions
• Secure and reliable connection
• Durable mechanical performance
• Good electrical performance
• Highly reliable design
• Quick and easy installation
• Optional kinked pins.

Uses of SFMC-139-L1-SM-D Connectors

SFMC-139-L1-SM-D connectors are primarily used for board-to-board interconnections, are suitable for applications that require transferring power and data/signals simultaneously, and are commonly used to interface with high-speed digital communication protocols. Other possible applications for these connectors include, but are not limited to, portable consumer electronics, medical devices, optical modules, embedded systems, automotive, In-Vehicle Infotainment (IVI), and aerospace components.

Working Principle of SFMC-139-L1-SM-D Connectors

SFMC-139-L1-SM-D connectors are powered and/or data signal-capable connectors. Electrical signals/data or power may be transmitted via one or more standard-size electrical contacts, typically arranged as single or multiple rows. The electrical configuration of these connectors is typically configured in a “pin and socket” mating relationship. The electrical contacts are inserted into a mating cavity, allowing a connector to be mated with a compliant nearby connector.

Each pair of contacts must be able to reliably establish a secure electrical connection when mated and must be able to tolerate the electrical and environmental stresses of normal operation. This is accomplished by providing a positive and reliable locking force between the mating electrical contacts. The contact locking force helps to ensure that the mating contacts remain tightly connected over a lifetime and is usually provided through a moulded pin-retention mechanism.

SFMC-139-L1-SM-D connectors are typically used with ribbon cables or printed circuit board(s). The connector is secured to the pc board or to the cable using screws. The connector typically contains alignment pins that mate with alignment holes in the receptacle for precise location. This helps ensure that the contacts of the mating connectors line up, ultimately ensuring that the mating electrical connection is reliable and of a high quality.

Advantages of SFMC-139-L1-SM-D Connectors

• Compact and lightweight
• High electrical performance
• High mechanical reliability
• Low contact resistance
• Secure and consistent connection
• Secure coupling between contacts of mating connectors.
