1102840-3 Heavy Duty Connector Housings, Hoods, Bases

Introduction

The 1102840-3 Heavy Duty Connector is one of the most commonly used types of electrical connections in industrial applications. It is designed to offer superior performance in harsh environments or locations that may be exposed to high vibrations. It features an IP 67 rating, which means it can withstand dust, dirt, and moisture. Additionally, the connector can also be used in temperatures ranging from -40 to 85 degrees Celsius. The connector is used to join electrical circuits, such as in control boxes, terminal blocks, and switchboards.

Construction Details

The 1102840-3 is a multipole connector consisting of two main components – the housing and the assembly. The housing is a cast aluminum shell with a durable plastic back-shell. It features four poles, and a strain relief for the cable. The assembly includes an insert consisting of two pre-installed keyed terminal blocks and three contacts on each side. The contacts can be crimped or soldered to the cables. Additionally, a cover is provided for protection from dust and moisture.

Application Field and Working Principle

The 1102840-3 is suitable for a broad range of industrial applications ranging from instrumentation to automotive systems. It is typically used to connect power distribution, control, and signal wiring. Additionally, it is compatible with several types of cables including LSF, PT, PVC, and LSOH.The connector works by allowing electrical current to flow between two points. The keyed terminal blocks prevent the wrong polarity connection from occurring. The contacts are also designed to provide a secure connection and reduce the risk of accidental disconnection. The cover also helps to protect the contacts from dirt and moisture, which can cause short circuits. The strain relief helps to reduce the risk of cable damage due to vibration or strain.

Conclusion

The 1102840-3 Heavy Duty Connector is a versatile electrical connection solution suitable for a wide range of industrial applications. Its keyed terminal blocks guarantee a safe and secure connection between two points. Additionally, its cover, strain relief, and other components work together to help minimize the effects of vibration and dust. The 1102840-3 is a reliable solution for harsh environments or challenging locations.
