SSQ-125-21-S-S Application Field and Working Principle

Overview

SSQ-125-21-S-S is a type of heat-shrinkable rectangular connector, widely used for a variety of applications such as accelerometers, pressure transducers, vibration sensors, and signal conditioning boards. It is designed to provide easy and secure connection for a wide range of signals between two or more electronic devices. It is capable of carrying up to 8A of current at a maximum voltage of 125 VAC/DC. The SSQ-125-21-S-S has a large surface contact area, so it can securely hold a variety of electronic components, ranging from resistors and capacitors to integrated circuits and pluggable connectors. Its design also makes it capable of withstanding shock and vibration.

Features

The SSQ-125-21-S-S connector is composed of three main components: the head, female plug and cable. The head is composed of two layers of a copper alloy that is plated with zinc, tin or nickel. The head has a number of threads that allow it to be easily and securely hooked up to a socket or receptacle. The female plug is a two-piece assembly that snaps together and tightened to the head. The cable consists of wire of the appropriate type and size, and is crimped with a metal ferrule. The SSQ-125-21-S-S has a maximum operating temperature of +125°C and a maximum tensile strength of 19.4 N/mm2.

Working Principle

The SSQ-125-21-S-S rectangular connector functions by two primary principles: electrical resistance and electrical current flow. The electrical resistance of the components creates a barrier that prevents current flow, while the electrical current is allowed to flow through the connector when electrical contact is made.The metal contacts of the SSQ-125-21-S-S increase the electrical current\'s ability to flow between the two points of contact. This type of connector also acts as a conductor, allowing the current to pass from one contact point to the other and from the component to the circuit board. This ensures a secure connection and helps prevent arcing and short circuiting.

Applications

The SSQ-125-21-S-S square shape and large surface area make it ideal for use in applications where space is limited and higher power is needed for stable operation. It can be used in a variety of industrial applications, such as measuring and sensor systems, high-speed communications and switching systems, HVAC systems, electronic components connections, and automotive and military applications. In addition, its heat-shrinkable design provides a superior seal against shock and vibration, making it the ideal choice for potentially hazardous environments.

Conclusion

The SSQ-125-21-S-S rectangular connector is a powerful and reliable device that can be used for a wide variety of industrial applications. Its design provides increased connection stability and superior resistance against shock and vibration, while its heat-shrinkable capability ensures a superior seal. With its ability to carry up to 8A of current at a maximum voltage of 125VAC/DC, it is a versatile connector that is reliable in a range of different environments.
