STMM-122-02-L-D Application Field and Working Principle Overview

STMM-122-02-L-D are a type of rectangular connectors, more commonly known as headers with male pins. The connectors have a linear connecting structure and they are derived from the contact design principles of horizontal surfaces. They are typically used in a variety of applications, such as in automated machinery, various industrial and electrical wiring needs, and medical equipment.

When used in applications, the STMM-122-02-L-D connectors can operate within a wide temperature range from -40°C to +85°C and can enable a high-speed transmission rate of approximately 2.0 GHz, with high peak power capability. The operating frequency is typically low with an impedance of up to 50 Ohms. Other features of these connectors include: four-terminal contact connection, a longer contact retention, an encompassing 360° EMI/RFI shielding, and various power rating options including 5V/0.5A, 40A/125V, and 200V/1.5A.

These rectangular connectors with male pins also include anti-vibration terminal designs, with a crimp technology that includes a two-pronged center as part of its five-pronged feature in order to accurately secure contact mating. Its spring contact retention also ensures that any wire inserted is securely in place and won’t come out due to vibration or a change in temperature.

In terms of the working principle of the STMM-122-02-L-D connectors, the general concept is a form of contact bonding with electrical/electronic applications using printable circuit boards, electrical or mechanical toys, and motor vehicles or machines. It is usually achieved through a process of interconnection and disconnection of a contact terminal that is integrated in the device. This, of course, relies on the general wiring concept, where all components need to be linked together for the device to operate properly and in order for the system to achieve the desired performance.

The circuitry comprising the STMM-122-02-L-D connectors is created using metal-to-metal contact surfaces. A carefully designed contact arrangement ensures that two or more points of contact are made and secured. The geometry of the connectors is standard and includes micro-shear type contact interfaces which mate two mating parts together and provide electrical continuity. This direct contact designed principle allows for a reliable connection and low resistance at every point of contact when used according to instructions. As a result, this low contact resistance enables the connectors to work properly with minimal signal losses and maintain quality performance even when switching between two different voltages and frequencies.

To summarize, the STMM-122-02-L-D connectors are rectangular connectors with highly reliable male pins that are typically used in applications such as automated machinery, industrial wiring, and medical equipment. The connectors are designed with a four-terminal contact connection, a longer contact retention, an encompassing 360° EMI/RFI shielding, and various power rating options. The working principle relies on a contact bonding process, with metal-to-metal contact surfaces and a carefully designed contact arrangement to ensure a reliable connection and low resistance at every point of contact.
