Rectangular connectors play an important role in electronics, providing a reliable connection between two electrical components and systems. Among them, SFMC-137-01-FM-D is an important connector. This article will focus on its application range and working principle.

SFMC-137-01-FM-D is a rectangular connector of the header, receptacle and female socket types. Commonly used in cameras, transceivers and communication systems, SFMC-137-01-FM-D is also ideal for breadboard connection and power supply. As a generic type rectangular connector, its insulators and terminals are made of thermoplastic UL94V-0, which is an excellent conductor and resistant to heat, impact and solvent. In terms of size, SFMC-137-01-FM-D has a width of 7.6mm and a thickness of 18.8mm.

The SFMC-137-01-FM-D is a low-profile type connector with four sockets and two rows of contact points. The bottom of the socket is equipped with fastening claws that can withstand a pull strength of 1N. The two rows of contact points are equipped with 3 and 5 contact terminals. The positive and negative poles of three contact points are demonstrated with red and blue color coding respectively, and the pure white color of the other two contact points shows their common potential. These contact points are made of brass. Since each of the contact points is rigidly connected to the copper wire, the entire contacts are firmly soldered. The SFMC-137-01-FM-D has a handle on the top with a maximum rated current of 0.4A and a rated voltage of 16V.

The largest application field of SFMC-137-01-FM-D connector is probably in transceivers and communication systems. In the transceiver, this connector is usually used to connect the antenna to the transmitting and receiving circuit, and to transmit the radio frequency wave to the receiving or transmitting antenna. With its outstanding features, the SFMC-137-01-FM-D is also suitable for multi-channel signal transmission in communication systems, which requires high accuracy and reliable performance from the connection.

In terms of working principle, the SFMC-137-01-FM-D has a two-tube design, which is effective for shielding the signal inside the wire. The inner contact point is connected to the pin of the two-row contact plate through a plastic insulation sleeve, and the outer tube is connected to the backplate through a metal spring clip. In this way, when the SFMC-137-01-FM-D is connected, the spring clip will be compressed, and the metal sleeve will be firmly embedded in the inner wall of the contact point. At this time, the contact point and the pin will be very firmly connected, thus ensuring that the signal can be accurately transmitted.

In conclusion, the SFMC-137-01-FM-D is a popular rectangular connector with a wide range of applications, especially in transceivers and communication systems. Its two-tube design provides a sound shielding for signal transmission. Its thermoplastic UL94V-0 material and contact points provide the connector with excellent heat, impact and solvent resistance, making it highly reliable and durable.
