HISTORY:
Sustainability is the name of the game! Anything (that has been tested and still functioning properly) should be repurposed creating saving in wasted Ee and reducing the poisoning our environment when items are buried in the earth at the local tip needlessly.
Never heard of Ee? It is a concept that creates a measurement of ALL things (not just electronics) that humans have made and the energy used in obtaining the raw material, processing the materials right through to a finished product and even should include the shipping of the item to the distributors/retailers.

This component is from the MATSUNAGA (Yokohama Japan) Frequency Converter, intended for laboratory use and providing up to 240V AC at a user adjustable variable frequency. Not only that, the AC voltage output could be varied across a wide range AND the user could set current limiting, so it could alter all three aspects of the AC output wavefrom, frequency, voltage and current limiting. I actually fired this gear up and it was working great but oh dear! What to do with it? Sure you could put up on the workbench but at that sort of weight it needed a lot of space and a good solid workbench. I decided a while back to offer this equipment as a complete unit "elsewhere" online for a while but there was no interest at all so I pondered over what to do with this equipment (to keep or not to keep) but it had a few things going against it.
As a complete unit it was EXTREMELY HEAVY, over 50Kg, which means that my arms are now 30cm longer from lugging this beast around the workshops! ... but more seriously, shipping would have been difficult to ensure safe travel AND very expensive. It also had other minor cosmetic issues because it is not easy moving such a monster around so it suffered scrap marks on various places of the all steel casing.
So, the "donor operation" has been undertaken and here is a nice old relay socket with the original relay (if wanted) If the socket did not have suitable wiring for your own relay, changing the underside hardwiring for each screw terminal is easy.
MATSUSHITA Electric Co. are a major worldwide company in the world of electronics which began operations in 1918 but they are now better known as PANASONIC.
MATSUSHITA (Japan) - Power Relay Socket
Made in Japan
Circa late 1990's
Part # 51011V
8 Way with screw terminals
Currently hard wired on the underside for a DPDT relay
OPTIONAL:
The originally fitted AC relay is also offered (included in the asking price)
MATSUSHITA
Part # AW5125
200V AC Coil (note the lower AC voltage of the coil)
DPDT switching 10 Amps
COSMETIC CONDITION:
USED
CLEAN
Undamaged relay case and base
Relay contacts bright and no "pitting" from arcing observed
TESTING:
Fully functioning whilst in the original test equipment but also tested after removal via my Variac (200V AC used for testing)
Coil is 6.13K Ohm
Activation voltage 200V AC
Very positive, audible "clunk" when operated
DC resistance checked on all of the DPDT relay switch contacts - no problems at all
Since testing I have now packed this socket with the optional relay (please tell me if you want the relay when purchasing) in a sealed clear plastic packet.
