Default More free and not so free industrial surplus

Free "GO" power line monitor. NIB
400vac 3phase
trips @ 3-4.5% unbalance in 4-5 seconds or 10% low voltage.

$5.00 each:
Furnas overloads. Trip levels vary.
Passive current relay. Opens dry contact at set ac current level. Works with only one or two legs connected as I recall.
Muliple turns thru core divides trip level.

More $5.00 items

NIB OMRON photoelectric switches.
E3X-DA11
12-24vdc
Use with fiber optics

These are neat versatile controls for hobby use.
Also have some optics with about a 6" stainless steel bendable probe for sensing in tiny spaces.
Pictures or specs if interest.

Hope I'm not abusing the forum.
There is no bottom in sight to my junk pile.
These are items that failed to sell on Ebay for reasonable price.
If I'm going to give something away, might as well be in a friendly forum.

What's there not to approve of? I don't see anything wrong here. All criteria are met.

Those Omron E3X sensors are some snazzy stuff. I recently used them to retrofit a mirror-making line, to sense mirrors coming down the line. I asked the customer if it would always be silver-backed mirrors, and they told me "YES. By the time the glass gets here, it's already got the silver backing" So I tested them out in the shop with mirrors, worked good, no problem. I get out to the customer's location and spend a whole 14 hour day installing them, and they turn the power on, guy comes back with a pane of clear glass to test with. I was sweating bullets. It worked! those E3X sensors will detect clean, clear glass within 8", right out of the box with no calibration. I was amazed. I was glad that I resisted the urge to freak out and say "hey, wait, you guys didn't say anything about clear glass!;" I just held my tongue and afterwards said "See there, did you ever doubt me?"

Changing the specs after the job is done?
Where's the smiley for, "just shoot me"?

ps, I had something similar happen once on an air conditioning job. The calculations were made, the machine was installed, it worked right, the price was paid, the workers were paid, the parts house was paid, and 3 days later a man that was never seen before the job or on the job phoned me to renegotiate the price of the job. LOL!!!

The funniest part is that we did the job for about 30% below "fair market value" because we operate with very low overhead. The customer couldn't have gotten this done by any legitimate corporation for less than a thousand dollars more than we charged. Then some in-law shows up and thinks it should have been be done for prices that were reasonable in the 1960's.
LOL!
