Rectangular connectors are widely used in today\'s electronics applications, ranging from manufacturing to medical device technology. The STMM-115-02-SM-D-RA, which is designed and produced by FCI, is a type of modular rectangular connector designed for high-reliability operation in demanding environments.

This compact device is fully compliant with the MIL-C-39012 Aerospace Standard that requires both mechanical and electrical performance qualification. The STMM-115-02-SM-D-RA is machined from a high-performance, environmentally-resistant material, and its design offers enhanced protection against EMI and corrosion.

The device is composed of two female and male header connectors with 6 to 15 positions mount pans. The STMM-115-02-SM-D-RA includes two standard connectors: two power poles and four signal connections. It also has an optional signal/power/ground redistribution strip. The device housing is made of high-impact and optically-clear thermoplastics, with an embedded EMI/RFI shield to protect the electrical components from EMI and signal interference.

The device is designed with a 2.54mm pitch. Its male and female connectors feature a single row of polarised pins which help ensure secure mating of the connectors. The pins have gold plating with a maximum current rating of 1.5A/pin. The device includes two mounting screws for secure mounting onto a PCB.

The primary application field of the STMM-115-02-SM-D-RA is in the aerospace industry. Due to its high-reliability and tough construction, the device is suitable for use in applications that require intensive electrical connection, such as high-voltage power applications, battery applications, fuel cell systems, and satellite imaging.

The working principle of the STMM-115-02-SM-D-RA is fairly simple. The male and female header connectors of the device are designed for mating and connection. The pins of each connector are polarized in order to ensure that the connection is secure. As the plugs are inserted, the polarized pins come into contact, creating an electrical connection. To complete the connection, two mounting screws are used to secure the connectors together.

In conclusion, the STMM-115-02-SM-D-RA is a high-reliability rectangular connector designed for use in demanding environments. Its gold-plated pins offer secure, high-current connections which are ideal for aerospace applications. The device is composed of two header connectors and an optional signal/power/ground redistribution strip which allows for easy and secure connections.
