I’m trying to identify these two connectors and what their part numbers are, but having no luck. There are no markings on the body. They appear to be utilizing quick-connector spade terminals.
Hello bart_nowak - welcome to the Forum community! The closest I found to your connectors was these Dynamic D-5200 connectors from TE. They are not exact equivalents, so you will want to compare datasheets to verify that these substitutes would be suitable for your application. When you click on one of these part numbers, scroll to the bottom of the page for mating connectors under the heading “mating products” and the contacts will be listed under the heading “associated products”.
You’re going to find something like this in our category of
Connectors, Interconnects > Terminals > Housings, Boots
Part Number: 171898-1 TE Connectivity AMP Connectors | Connectors, Interconnects | DigiKey
Part Number: 171897-1 TE Connectivity AMP Connectors | Connectors, Interconnects | DigiKey
The associated terminal contacts for these are located on the bottom of the page on these connectors.
