The Simplest Sensor Endcap Design.

Have you ever noticed that there are no screws or threads used to lock our sensors together? Thanks to our endcap design.

All of our underwater sensors use a castellated endcap design. This enables the endcap to mechanically secure in place without the need for screws or threads.

When we designed our first subsea sensor, we wanted to make sure it could be easily disassembled following months or years of deployment in seawater.

We also wanted to ensure it could be taken apart simply, without the need for special tools/heatguns etc. Subsea housings using screws, threaded endcap clamps or nylon cord locking mechanisms can suffer from salt deposits which can make them extremely difficult to take apart once they have been deployed for any length of time in salt water.

Hence we created the castleated locking mechanism with a metal securing clip. This mechanism, regardless of how long the sensor has been deployed, is quick and simple to take it apart. It also does not require any tools to take it apart.

Today this mechanical arrangement is used in all of our underwater sensors.


Today we’re going to put together an endcap which will show how simple it is.

We’ve got here a wire clip, an end cap and a body tube.

The body tube has a flat section top and bottom and round sections left and right.

The end cap also has a north marker on one of the flat sections. If we place that into the body tube so it all lines up. Then ready to put the wire clip on.

You simply push it over the side and then stretch it over the end cap as shown.

To take the endcap off we press a finger up against the wire clip on the side with the north marker. We then take a finger where the gap is, push one edge of the wire clip out and lift off at the same time.

Thank you very much for watching and we hope to see you again.
