66 -- VACUUM FEEDTHROUGH RECEPTACLES AND PLUGS SOL 8-W-5-06-84776 POC Contact Patricia Fundum, GP26-V, 205-544-8436/Contract Specialist, or Jane Maples, GP26/Contracting Officer NASA/MSFC plans to issue a Request for Offer (RFO) for Ceramaseal Vacuum Feedthrough Receptacles and Plugs -- This procurement is being conducted under the NASA/MSFC MidRange Pilot Test Program approved by the Office of Federal Procurement Policy on April 16, 1993 -- NOTE: The proposed contract is planned for other than full and open competition with Ceramaseal, 127 Hatters Lane, Simpsonville, SC 29681 -- ITEM 1: Ceramaseal part number 10769-01-A, Quantity 10 ea., Type T thermocouple feedthrough receptacle designed for use on a vacuum chamber, capable of mating with a moisture resistant air side plug and a vacuum compatible plug. When connected to the air side plug the assembly must provide a moisture seal at their interface using a knife edge design. It must have 37 pins to provide 18 thermocouple pairs (18 copper pins and 18 constantan pins) and one spare pin for grounding. It must fit a 1.31 inch diameter hole. It must have a viton o-ring for the vacuum seal and be capable of withstanding welding for higher vacuum capability requirements and pressure requirements to 1000 psig. It must fit into a flange plate .42 inches thick. It must have conductor isolation up to 600 volts and be able to conduct 7.5 amps on each pin. The vacuum leak rate of helium must not exceed 1 x 10-9 atmosphere cubic centimeters per second (atm cc/sec). The operating temperature range of the feedthrough receptacle must have a low extreme of -200oC and a high extreme of +200oC. The sealing dielectric material is to be ceramic or glass-ceramic bonded to stainless steel, and the minimum sealing process temperature must be greater than 550oC (to achieve high vacuum, welding, and pressure capability). The exposed pin length beyond the insulating material is to be no more than 0.5 inch to maintain support. The external housing is to be made from 304 stainless steel for corrosion resistance. Plug attachment is to be a push-pull engagement mechanism. The feedthrough receptacle also must be able to accept Deutch 37 pin plugs. -- ITEM 2: Ceramaseal part number 10769-11-A, Quantity 5 ea., Type T thermocouple feedthrough assembly (including receptacle with air side & vacuum side plugs and 40 gold plated copper contacts and 40 gold plated constantan contacts and a contact insertion and removal tool) designed for use on a vacuum chamber. The air side plug must have an insert that surrounds the connecting wires when inserted in the plug to provide a moisture resistant seal when assembled. It must also provide a moisture seal when connected to the receptacle at their interface using a knife edge design. The air side plug insulator mating face, back face, and the moisture resistant grommet back face shall be numbered for ease of wire assembly. The vacuum side plug materials must be compatible with high vacuum systems. The vacuum plug insulator mating face and back face shall be numbered for ease of wire assembly. Both plugs must provide a wire bundle strain relief clamp to hold wires securely. Both plugs must use rear release type contacts. It must have 37 pins to provide 18 thermocouple pairs (18 copper pins and 18 constantan pins) and one spare pin for grounding. It must fit a 1.31 inch diameter hold. It must have a viton o-ring for the vacuum seal, and be capable of withstanding welding for higher vacuum capability requirements and pressure requirements to 1000 psig. It must fit onto a flange plate .42 inches thick. It must have conductor isolation up to 600 volts and be able to conduct 7.5 amps on each pin. The vacuum leak rate of helium must not exceed 1 x 10-9 atmosphere cubic centimeters per second (atm cc/sec). The operating temperature range of the feedthrough receptacle must have a low extreme of -200oC and a high extreme of +200oC. The sealing dielectric material is to be ceramic or glass-ceramic bonded to stainless steel, and the minimum sealing process temperature must be greater than 550oC (to achieve high vacuum, welding, and pressure capability). The exposed pin length beyond the insulating material is to be no more than 0.5 inches to maintain support. The external housing must be made from 304 stainless steel for corrosion resistance. Plug attachment must be a push-pull engagement mechanism. The feedthrough receptacle also must be able to accept Deutch 37 pin plugs. -- ITEM 3: Ceramaseal part number 10769-15-A, Quantity 5 ea., Instrumentation feedthrough assembly (including receptacle with air side & vacuum side plugs and 80 gold plated copper contacts and a contact insertion and removal tool) designed for use on a vacuum chamber. The air side plug must have an insert that surrounds the connecting wires when inserted in the plug to provide a moisture resistant seal when assembled. It must also provide a moisture seal when connected to the receptacle at their interface using a knife edge design. The air side plug insulator mating face, back face, and the moisture resistant grommet back face shall be numbered for ease of wire assembly. The vacuum side plug materials must be compatible with high vacuum systems. The vacuum plug insulator mating face and back face shall be numbered for ease of wire assembly.

The sealing dielectric material is to be ceramic or glass-ceramic bonded to stainless steel, and the minimum sealing process temperature must be greater than 550oC (to achieve high vacuum, welding, and pressure capability). The exposed pin length outside the sealing material is to be no more 0.5 inches to maintain support. The external housing must be made from 304 stainless steel for corrosion resistance. Plug attachment must be a push-pull engagement mechanism. The feedthrough receptacle also must be able to accept Deutch 37 pin plugs. -- ITEM 4: Ceramaseal part number 12307-03-A (package of 5 each), Quantity 106 pkg., Gold plated copper contacts which are individually coded for identification and are designed for rear release type plugs designed to fit item 1 listed above. -- ITEM 5: Ceramaseal part number 12638-03-A (package of 5 each), Quantity 64 pkg., Gold plated constantan contacts which are individually coded for identification and are designed for rear release type plugs designed to fit item 1 listed above. -- Specifications will be contained in the RFO -- F.O.B Destination Delivery at MSFC is to be accomplished within 3 months after award -- The supplies required are believed to be available from only one source and no other type supplies will satisfy the needs of the Government -- Interested firms have 15 days from the publication date of this synopsis to submit their qualifications/capabilities in the critical areas mentioned above, along with a request for a copy of the RFO -- Requests for copies of the RFO must be submitted in writing -- Transmission by facsimile to 205-544-9081 or by Internet e-mail to patricia.fundum@msfc.nasa.gov is acceptable -- Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis -- Responses received after the 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered -- Oral communications are not acceptable in response to this notice -- A determination by the Government not to compete this proposed contract, on a full and open competitive basis, based upon responses to this notice, is solely with the discretion of the Government -- This sole source requirement, specific make or model number described is based on predominant experience and insufficient competitive technology -- RFO will be released on or about 15 days after publication in the Commerce Business Daily (CBD) -- Proposals will be due 30 days after issuance of the solicitation -- Firm date for receipt of offers will be stated in the RFO -- Documents related to this procurement are available over the Internet -- The documents are in ASCII format and reside on a World-Wide Web (WWW) server, which may be accessed using client browsers, such as, MOSAIC -- The WWW address, or URL, of the MSFC Procurement home page is: ''http://procure.msfc.nasa.gov''.
