For wiring test
From Japan

With sequencer replacement, the program on the congestion detection part on the conveyor has gone out. It seems to cost 200,000 yen by programmer arrangement, so it was necessary to respond with an external timer inside the company. I need 1a1b. After searching, this relay of 4c was displayed at the recommendation and it was half price, so I bought it. I bought it without understanding the point of contact, but I immediately understood by the tester. Price is cheap, Panasonic is safe, recommended.

Because it is not put in inventory at the general electronics store, it took time and labor to find, so the price was also cheap It was good for me.

Due to the large stroke compared with onboard small relay etc., Although the speed of operation drops, when looking at the number, the appearance is also spectacular, You can also enjoy operating sounds.

Machine control on control panel

This relay has compatibility and durability is satisfactory. I feel that the accuracy is not inferior to that of the same type of certain manufacturer. And the performance in terms of cost is Pikaichi. Because of the structure of the machine, it becomes a consumable item because of frequent exchange This price is very appreciated.

The power switch attached to the equipment is large and heavy, so switch it down so as to use the relay switch to turn it on / off.
