Circular Connectors - Contacts are an integral part of numerous applications combining electronic machinery in modern engineering. The SC20WL-3S25 is a type of circular connector featuring contacts, that offer simple and reliable fire-safe wet mating connectors in a variety of sizes and configurations, specifically designed for safety critical applications. It is a convenient, reliable, and cost effective solution for a wide range of applications.

Application Field:

The SC20WL-3S25 rectangular connector is a single-piece connector, composed of moulded plastic with an encapsulated contact array and gold plated contact points. The contact geometry enables the connector to be used in applications including gas, oil, and hazardous area systems. It can be used in automobile lighting, fire alarm systems, radiators, anti-theft devices, and communication systems, as well as medical equipment.

The connector’s design also makes it suitable for applications in extremely harsh environments. It is resistant to extreme temperatures, moisture, and voltage. Furthermore, its short contacting distance ensures high contact stability, making it ideal for use in hazardous, industrial, military, and medical applications.

Working Principle:

The SC20WL-3S25 Circular Connector features contacts that are mechanically independent from the body. Each contact has a unique spring, which consists of two spring elements. The upper element is typically made of stainless steel while the lower element is made of brass. A conductor passes through the gap of the two elements, securing it in place and preventing it from sliding out. This allows the contact to exert a force against the conductor, creating a secure connection.

The contacts are secured within the connector\'s body in a two-point locking system using a contact retention feature. In addition, the contacts are held firmly in place by a locking mechanism, offering superior shock and vibration protection. This ensures that the connectors remain reliable and durable in extreme environments.

The SC20WL-3S25 offers a variety of contact configurations, which are designed to support various current ratings. The contacts are made from high quality materials such as copper, brass, gold, and aluminium, and are compliant with European standards, ensuring compatibility with products from other manufacturers.

In conclusion, the SC20WL-3S25 circular connector is a reliable, cost effective and versatile connector, designed for use in a wide variety of applications. Its unique contact design and locking mechanism offer superior protection from shock and vibration, making it an ideal choice for hazardous, industrial, and medical applications.
