It is compact when viewed from the contact capacity. Also robustness is good. It feels and improvements that hard to look at a diagram of the contact. Because it is not company work Remove company name of the check.

Machine control system repair
From Japan

Because it is being used in the machine control system that repair has in stock at all times, but this time because there is no retail store in the neighborhood it was purchased in Monotarou's. You can use normally. Also those of the other relay buyers have been written, but because I think that leg of the relay is able to bend at the time of transport, I think that it may be equal to protect refers to the Styrofoam.

Synchronous on / off control of the load connected to the tenant circuit.
From Japan
On 2011-09-11 23:14:09
Normally, I think that it is a place to choose "MY ~" even from a large number of choices because of the price. But I'm making it "LY ~". <Good point> Unlike "MY ~", the legs for the motion coil are "vertically oriented", points easy for beginners' workers to educate, "few mistakes" on construction . <Points that were bad> ① Because I ordered it with individuals this time, "Restoring one leg, one bent slightly", restoring on site, with a radio pliers. It is exaggerated to say "bad points", it is not a problem. I plan to use it in the future. ② Compared to "MY ~", "Price is high" and "There are few options" points. Apart from expensive prices, I think it would be better to increase the choices. For example, if it is "MY ~", such as "with CR circuit" lineup that is normally taken.

As a replacement part.

I would like you to consider bulk selling on the box. Individual packaging takes time and effort to peel off as the number increases, and legs often bend.
