Here is an O'Keefe Controls air proximity sensor, model or part # OKC-818. The body tube is supposed to be Stainless, the connector is supposed to be Delrin and the tail end is supposed to be Brass. The input air is up to 10 PSIG and should be CDA, or clean dry air, filtered to 1 micron. Response time is 1 millisecond. maximum distance from part being sensed is 1/8". There is lots of info on data sheets included. This is new old stock. Has the vendor bag and data sheets but no other vendor packaging. The label on the bag is loose. No tubing or fittings included. I have a few available. Free shipping via USPS 1st class package / box with tracking #. If you have any questions, please let me know. Thanks.
