Hold-Down and Release Mechanisms for Space Applications: HDRM's, Pin Pushers, Pin Puller and other Space Mechanisms

Non-explosive light, medium, and heavy-duty HDRMs, pin pullers and pin pushers for spacecraft satellite hold down and release. Special-purpose ultra-lightweight small form-factor split-spool release mechanisms for CubeSat and NanoSat deployment as well as antenna, solar array, reflector, boom, and mast release.

Series 06

Hold-Down and Release Mechanisms are electromechanical devices used in the deployment of satellites and other payloads in space. Supplied in various formats and measured-release preloads, the devices are optimized for foolproof release-reliability with built-in mechanical and electrical redundancy. In non-pyrotechnic HDRMs, the planned release of the deployable satellite/payload is activated by a pre-determined value of electrical current to a fuse-wire system which causes the wire to break under tension and allows a pre-loaded mechanical bolt to actuate.

Glenair's line of low-shock, redundant and non-redundant space mechanisms includes both HDRM devices as well as a family of pin pushers and pin pullers. Customer-defined housing and mounting configurations are available. Consult factory for specific device TR level and qualification test reports.
