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 single event release mechanisms with refurbishable fuse wire for CubeSat and NanoSat deployment as well as antenna, solar array, reflector, boom, and mast release.

Series 06Series GSS500

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 North American manufactured HDRM devices as well as an EU Series of HDRMs manufactured in accordance with ESA standards and local market requirements. We also offer 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.
