Description
Reference MPN listed for SA-PJ-3. Final fit needs the drawing or BOM. If mounting is missing here, confirm it from the drawing or mating requirement. Material is listed as {'Contact': 'Brass/Beryllium Copper/Gold Plating', 'Body': 'Stainless/Passivate Treatment'}. That is useful for review, but it does not replace full project stack-up confirmation. Use this page to shortlist before RFQ, not as the final sign-off.
Use this page to shortlist before RFQ. MOQ 200+ custom production and supply path are confirmed after drawing/spec/BOM review; no spot stock is assumed.
