Your guide to Hammond enclosures

Enclosures are used to house electrical circuits providing protection against the environment and safely housing the circuit. They come in all shapes and sizes, which can sometimes make it overwhelming when trying to find the most suitable enclosure. We stock over 1000 different Hammond enclosures and created this guide to assist you in finding the best option.  

 

Enclosures are typically made from 2 materials; metal or plastic. Plastic enclosures are typically lower cost and lightweight making them suitable for a huge range of applications. They are commonly made from polycarbonate, ABS or PVC, and can easily be moulded or modified into various shapes and sizes. The material is also non-corrosive against rust and chemicals making them suitable for use in harsh environments. Plastic enclosures also let EMF and RFI waves pass through which can be a significant factor if your application needs to send or receive radio signals. 

 

Metal enclosures are often more costly and are typically manufactured from aluminium. They are more durable than plastic making them suitable for high-impact environments and feature strong resistance to temperature. Aluminium is resistant to corrosion and rust which also makes them a great option in harsh environments. Metal enclosures can resist some EMF and RFI signals, which can limit its application when used with certain transmitting and receiving equipment. 

 

How to choose the correct enclosure

The first step is to determine whether a plastic or metal enclosure will be best for your application. Once this is decided you can analyse whether you require any specific features for example; flange, RFI shielding, PCB guides, IP rating, standoffs etc.

The final step is to determine the enclosure size. You can use the category filters to choose the most suited enclosure outer dimensions for your application. It is also important to consider the internal dimensions required for your application. Our website features a technical drawing for each Hammond enclosure which shows the full dimensions including the internal dimensions.
