Electronic – this component? 1970s electronics

componentsidentificationvintage

I broke it while trying to repair a nearby component on a 1970s board. It has two wires at one end that look like they are going to a coil and two axial wires. One of the axial wires came out with some pieces of glass.

The only markings are "P/F" which mostly likely means Philco/Ford.

The "silkscreen" was marked with "S1" and nothing else.

The end with the two coil wires is angled at 45 degrees I presume to indicate polarity.

I also need a way of working out what value it is so I can get a modern replacement.

Thanks!

What Is This Component?

It's the outer magnetic coil of a reed relay. The two axial connections connected into the glass body are for the reed contact: -

The picture above shows the coil (bottom) and a couple of reed contact options with the top being a SPNO. The lower one looks like a 4PNO device But they could easily be NC types.

Here's an article that shows this explanatory picture: -

Good luck.
