Application Field

The 1509-ST Barriers provide a quick and easy connection for reliable applications. It is also suitable for hazardous and marine environments, such as in instances where high pressure and contamination is present. It has a soldering capacity of 120A and a voltage of up to 120V AC or 260V DC voltages. Some application fields of 1509-ST barrier Blocks include battery storage, relay control, lighting control, security system, HVAC system, motor packages, harness packages, automotive, telecommunication, and industrial control.

Working Principle

The Barrier Blocks are designed with two main parts, an upper housing and the lower housing. The upper housing includes the base and the actual terminals, which are spring-loaded in order to create the electrical connection. The conductive materials embedded in the base protect the contact from oxidization and rusting. The bottom housing is composed of a plastic pin housing and metal strip, which are mounted in order to hold the electrical wires.

When the two housings are placed together, a spring-loaded plunger mechanism begins the connection between the two terminals. This mechanism works by pressing the plunger down and the spring brings the terminal back up to make the connection. The contact pressure is maintained at a high level to ensure that the connection remains firm. This ensures that a reliable connection is made and the component remains safe from oxidization and corrosion.

These devices come with various contact sizes and its operation temperature varies from -20°C to +80°C. Furthermore, the contact resistance of 1509-ST Barrier Blocks is 10mΩ and rated 5000 cycles, which guarantees its reliability and long lifespan.

Conclusion

To sum up, the 1509-ST Barrier Block is a reliable and durable connection device that is suitable for various applications, such as in the medical and aerospace industry. It has a soldering capacity of 120A with a voltage up to 120V AC or 260V DC voltages. The contact resistance of 10mΩ and rated 5000 cycles make it a dependable connection for long lifecycles.
