Hi I am looking for a high limit sensor, part number 9920-400342. It has two wires and a 4 pin connector do you have such a part Thanks Murdo

Rosie answered:
Hello, This one is not currently in our inventory but yes we can get it in from the US. Lead time is approx 1 week. Its a slightly more expensive sensor than some of the others and I anticipate it would be around £60 inc vat.
