NASA Standard Initiator (NSI) and PC-23 The NASA Standard Initiator (NSI) and its commercial equivalent, the PC-23, were developed by Chemring Energetic Devices (CED). The NSI’s heritage dates back to the Apollo program and today, CED remains the only NASA-qualified NSI manufacturer in the world. Contact Separation and Explosive Bolts Chemring Energetic Devices' separation bolts are designed and manufactured for use in applications where rapid structure separation is demanded. They are low shock and highly reliable for use in launch vehicles, satellites, and payload systems. Contact Separation Nuts Chemring Energetic Devices' separation nuts are designed and manufactured for use in applications where rapid structure separation is demanded. They are low shock and highly reliable for use in launch vehicles, satellites, and payload systems. Contact Thrusters Chemring Energetic Devices’ thrusters have been long used in many types of launch vehicles. Thrusters push apart structural elements or eject fastened components and are designed to withstand the severe environments of aerospace use. Contact Pin Pullers and Pin Pushers Chemring Energetic Devices' pin pullers and pin pushers are controlled-release mechanisms used in applications requiring instant detachment of structural fittings, mechanisms, rods, cables, booms or parachutes. Contact Cutters Chemring Energetic Devices' cutters have demonstrated high reliability on countless space missions for over 20 years. The cutters are designed for robustness and can be used in space as well as in deep submergence applications. Contact
