Identify component in 737 cockpit window please

[Jimbo2Papa]

I've noticed these tucked away in the frames of cockpit windows of 737s - red arrow pointing to it.
Pure curiosity as to their function.
Looks like a small white bulb on a wire.

Thank you in advance.

Total guess.

DV Window 'closed' prox sensor?

Pure guess, but is it a connector for a heated window?

[Jimbo2Papa]

No, the heated window connectors are further back.

Thus;



Don't think they're " Window Closed" sensors as I believe they can move.

That's the glass itself. There is a black power feed cable with connector that runs to the DV from the rear of it. That wiring runs along the base of the window. It may be a protective grommet for that you are seeing. Should be one towards the rear too.

[Jimbo2Papa]

So Turin was correct? It's a power cable for the DV Window Closed sensor?

It’s possibly a customer option that I’ve never seen but the 737 doesn’t have a “window open” warning. Until apparently you get to about 90 knots, when, if it’s unlocked.............
The white plug like device? Sorry, no idea.

window heat elect. connector
r. no warning light for pilot s side window open.

Or window overheat sensor

It's for the window heat. There is no sensor for an open cockpit window. I guess Boeing figured you would hopefully know if the window was open and wouldn't need a caution light.

[Jimbo2Papa]

So Window Heat connector it is.
Well done golfbananajam after all.

The cat's curiosity is assuaged.
Thank you gentlemen.

BSD - I chuckled at your comment about the Window Open Warning occurring at approx 90 kts.

Boeing did a training film years ago about such an eventuality...

Those two wiggly things the arrow is pointing at are the temperature sensors for the window heat. There are actually two separate sensors with a total of three wires/connection points (they share a common wire). This is so that if a single sensor fails (it does happen) they can switch to the second sensor without having to replace the whole window.

Thanks for that IRR

AKO: I guess Boeing figured you would hopefully know if the window was open and wouldn't need a caution light.

They put a warning on the triple though.......

I think they put a stencil on the window frame in big letters.. WINDOW IS OPEN! 😁

TURIN, and their is me thinking that pilots are meant to be clever.

It's a whosywhatsis or a thingamajig or whatchamacallit
