Need Datasheet for New Product Engineering P/N 812-203 (relay?)

[(Edward) Allen Monahan]

Size: Body: 25mm L x 15mm W x 9mm T; Overall: (with terminals) 32mm L x 15mm W x 13mm T

New Product Engineering was located in Wabash, IN at the time of manufacture. I have not been able to find any reference to this company (or division of another company or corporation).

The photos are crude but I hope they help.

You're right, I can't see any detail in your pictures, you might want to try again.
Are you SURE this was a company called 'New Product Engineering'?, and not some prototype of some known
manufacturer?
What did they come out of? Or are they just loose in your parts bin? It would help if we knew what these
devices were originally installed in.
If this was me, I'd start Googleing information about manufacturers that had facilities in Wasbash, IN, and
try to find out what other company probably bought them out.
Somebody in Wabash would know about this company, a commerce commission or even a local library.
I don't know if you have a bad one, and you're trying to replace it; or if you have box full of them and want
to know what they are.
I'm half thinking they were made by some known company as prototypes, and were just labeled for their 'new product engineering' Dept for test(?) Or possibly specifically designed as a proprietary product run for some special order for some particular manufacturer(?)
Can you tell us any more about how you got ahold of this device?
I too, have never heard of a company by that name, and I've been doing relays for a lot of years.

Looks like a very old style relay, if you need to replace it it may be quicker to do a little reverse-engineering, and if it is shot, open it up to help with what you need, you may have to get creative with a means of mounting a miniature relay in place of the old one.

Thank-you for your replies. I did try to find any reference to "New Product Engineering" in Wabash prior to my post with no results. I have several of these "relays" in my junk box that were acquired with some other junk box parts I wanted. I have a project in which I was considering using them. Nice to know coil and contact ratings prior to including a device in a project. I just did some measurements. Of the 8 terminals on the relay, terminals 4 to 5 (my numbering) have 761 Ω between them. The rest have no continuity to any other terminal, so I am assuming that the relay has 3 sets of NO contacts. Next I will try to power the coil from 5 to 12 VDC and see if I get contact closure, then monitor for temperature rise. I was hoping for 2 sets of NO/NC contacts.
