PIR sensor for lights to mount on 20mm conduit box?

[sparkybird]

Hi all

I've had a quick google but it didn't come up with anything. Do these exist?

Hopefully someone might know. It would make for a much neater job!

Cheers

Oh, must be suitable for outdoor

Try Googling besa pir

What size box is the 20mm conduit going into?

Thanks Ban for speedy reply- but the Danlers one is surface mount on a square box - which CAN be fixed to a besa box so not much help as I need an outdoor one. Besa box is fixed to vertical wall.

I never realised that the round conduit boxes were called besa boxes - is that just a trade name like Hoover??

Sorry if I didn't make it clear. I'm looking for a PIR which would mount on a round conduit box (besa box). 20mm conduit

Oh, maybe this is the thing??

Not sure about the IP rating though...

Might be better off terminating the conduit in a 200 x 200 IP65 box.

Hi Alarm - yes, I think that's plan B!

The conduit and boxes are already in place so looking at least disturbance options first

No: it stands for the British Electrical Systems Association.

I think I fitted an IS 180 to a round conduit box that was flush with the wall.

This might be OK

I fitted one of those on Wednesday! The spacing of the fixing holes is not in the bumpf, but is stamped into the plastic on the back of the unit. I seem to remember 36mm, could that be right?

Besa boxes are 50.8mm centres.
