As Clarky says it's quite normal, you're not the first to ask though...

I always thought it was some kind of weight on a rod which detects if the image was taken portrait or landscape orientation? The sensor wouldn't make such a loud clunk would it?

It is the SR mechanism. The sensor isn't restrained from moving until the moment of capture when it is held in place (or moved to compensate for shake) by electromagnets around its perimeter. At other times it's free to move around and make thudding noises.
Pentax missed a trick by not mentioning this in the manual, new owners worried by the thud is probably one of the most frequently covered topics on these boards.

It's not "just" the sensor though, it's also the housing that it sits in.

Perhaps you don't have 'sensor clean at start up' turned on because you should feel it vibrate quite a bit.

Ken - are we talking the small amount of slack in the SR system when it's not powered or the self clean function.walkeja wrote:

I have to say I have not heard the clunk on mine and I am certainly not going to shake it hard so I can.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

If i turn my pentax k10d to the side to take a portrait shot something moves inside a little. You can feel a little thud inside. Is this normal?
