Nos microswitch ps-1, PA3, trb set complete works
New Old Stock, in original boxes except the PS-1 which is in its original bag. Set includes 1 each of the following, P/N PS-1 proximity sensor, PA3 Proximity switch amplifier module (8 pin octal relay base plug in), TRB relay and amplifier base which has 2 - 8 pin octal relay bases/ 1- 12 vdc DPDT relay rated at 10 amps/ and the power supply transformer (115 vac to 15 vac) that operates the amplifier with terminals to connect the incoming 115 vac and also to connect a light for use with an emitter / detector light switch (such as the one you would have across a doorway or conveyor to detect moving parts that are not metallic) The PS-1 proximity sensor has what I'm guessing is about a 10' 2 wire lead to connect to the amplifier. All together these would be used to sense metallic objects (steel mostly)passing on a conveyor, or a door closure, window or whatever passes within an inch or so of the head. There is a fine and coarse adjustment on the amplifier that can change the distance. I passed a screwdriver in front of the sensor and it worked out to about an 1 1/4". I figure with a larger piece passing by it would work farther out. The whole set is new old stock, never used or installed except for the testing that I did to confirm that it works. It works great and comes with our Guarantee of 30 days from receipt.
I also have PS-1 Proximity switches, PA3 amplifiers, TR5-14 amplifiers and a complete (tested and guaranteed) but used system as described above. Email us and we'll list what we have for you.
