IP44 or IP67 Plugs: What Type Shall I Choose?

Which of the outdoor plugs should I go for? We at TCAD weigh up the differences.


We at Total Control and Distribution offer a wide variety of plugs and sockets for internal and external use. These are designed for use in portable power supplies and wall sockets. Our IP44 and IP67 rated sockets are supplied by Lewden. So, what’s the difference between the IP44 and IP67 sockets may you ask?

To tell the difference between IP44 and IP67 varieties, it is easy to note that the first type is splashproof. The second of the named types is waterproof.

IP44 standard

The IP44 standard plugs are splashproof and the UK versions are manufactured by Lewden. They are also effective against hazardous parts greater than 1 mm to 3 mm. Sockets are sealed with a flip-top lid. Its pin arrangements are similar to the small AC plugs used in theatrical lighting with round pins.

The IP44 standard system is splashproof if water approaches the socket from any angle. There are two tests: a ten-minute one with the shield closed, and a five-minute one with the socket shield opened.

IP67 standard

For wet locations, the IP67 standard is the better of the two kinds discussed. This offers more protection against wet surfaces and dust. The first part of the 66 refers to the level of Solid Particle Protection, and ‘6’ is the highest level.

Where IP67 plugs differ from their IP44 brethren is the number of pins. They have four round pins instead of the usual three. Shields keep the shield airtight when the socket is not in use.

Who makes IP44 and IP67 plugs?

Our plugs are made by Lewden but other manufacturers include Gewiss and ABB.
