This is a new Radiall ARINC 600 NSX BPX Series 150 × #22 FR/FR Insert for Cavities A & B w/ Size 22 PC Tail Contacts- This was carefully removed from a new in the box ARINC 600 NSX series connector.
We had a client contact us who needed only the insert, therefore we removed all the components from the connectors, like the Inserts Retention Plates, Polarization Retention Plate, Insert for Cavities A & B, Insert for Cavity C and are selling them individually here on eBay.
