Rectangular Connectors - Housings

The 87922-3 connector is a specialized rectangular housing with an additional power contact in-between two contacts and a hinged lid. Due to their specific design, 87922-3 connectors are highly reliable and suitable for a variety of application fields and operating conditions.

Application Fields

The 87922-3 connector is ideally suited for use as the interface between relay controls and the associated contactors. This allows for fast, safe and precise operation of the contactors due to the higher current throughput afforded by the 87922-3 connector. It is also well-suited for industrial automation. Applications include communication and automation networks, office and factory automation, and process control.

The conectors are also ideal for use in panel mounting. They provide a strong connection and provide superior vibration and shock resistance, while requiring low installation space. The slotted housing makes it easy to access and repair the connectors. The 87922-3 connector is also suitable for use in medical and aerospace applications.

Working Principle

The 87922-3 connector consists of a two part male and female housing. The female housing has a ground contact, power contact and four insert contacts, while the male housing has a ground contact, power contact and three insert contacts. The ground and power contacts are connected by a connecting spring. The eight insert contacts are held by spring-loaded pins. When the lid is closed and the contacts are aligned, the contacts make contact and a secure connection is established.

The 87922-3 connector has an integrated safety feature, which prevents accidental contact with the power contact while the connector is connected. The contact housing is divided into two halves, and the power contact is contained in the lower half, so when the connector is plugged in, the female contact is protected from accidental contact with live power lines.

Advantages

The 87922-3 connector offers a number of advantages over traditional connectors. Its dual current contact capability allows for higher current transfer rates, meaning faster switching speeds for contactors. The 87922-3 connectors are also very reliable and resistant to corrosion and shock. The connector design is such that it can be used in difficult-to-reach places and extreme conditions such as high temperatures and humid environments.

The 87922-3 connectors also offer excellent electro-magnetic compatibility, totally insulating the power contact from the insert contacts. This helps suppress both crosstalk and electronic noise within the system.

Conclusion

In conclusion, the 87922-3 connector is a highly reliable and versatile housing connector. It is ideal for use in industrial automation, panel mounting, medical and aerospace applications and many more. The additional power contact and easy accessibility make the 87922-3 connector an excellent choice for a variety of applications. Its high current capacity and superior design make it a safe and effective method for connecting relay controls to contactors.
