Power entry connectors (PECs) offer a convenient and efficient power solution for a variety of applications. The 66-SSF-020-0-14 is a standard, field-tested and reliable PEC made of a durable, high-temperature plastic resin and with a UL Recognized or CSA Certified set-screw locking feature. In this article, we discuss the application field and working principle of the 66-SSF-020-0-14.

Applications

The 66-SSF-020-0-14 is commonly used in applications that require a secure connection to an external power source. Examples of these applications include: electrical controls, enclosure systems, medical, lighting, antenna systems, military, and industrial equipment.

The 66-SSF-020-0-14 is a type of low-voltage PEC with a maximum rating of 30 amps and a voltage range of 125VAC, 250VAC, and 480VAC. It is UL recognized and offers a variety of operating temperature ranges, including -20°C to 80°C. The PEC is also UL Rated 4X. This rating makes it suitable for use in hazardous locations and for washdown applications.

Working Principle

The 66-SSF-020-0-14 PEC features a set-screw locking design, which is how it secures itself to its power cord. This locking feature consists of four set-screws with small, triangular-shaped indentations that are strategically placed on the housing. Once tightened, each set-screw compresses against the power cord, providing a secure connection.

In addition to its locking feature, the 66-SSF-020-0-14 also features an integrated strain-relief system that reduces the mechanical stress placed on the power cable. This is accomplished via a specially molded zinc-plated spring-steel claw and nylon nut. The spring-steel claw is designed to grip the power cable and provide a tight connection, while the nylon nut helps eliminate any slack in the power cord.

The 66-SSF-020-0-14 PEC also incorporates a spring-loaded sealing guard that helps protect against dust and debris. The sealing guard is held in place with two sturdy metal clips that are corrosion-resistant. This helps ensure that the PEC remains secure and protected in its application.

Conclusion

The 66-SSF-020-0-14 is an ideal solution for power entry needs in a variety of applications. It features a reliable set-screw locking feature, an integrated strain-relief system, and a spring-loaded sealing guard that shields it from dust and other debris. This makes it a durable, cost-effective solution for a variety of applications.
