About
EBAD’s NEA® Model 9040 Miniature is a non-pyrotechnic Hold Down & Release Mechanism (HDRM) designed for the spacecraft market. It supports release loads up to 250 lbf (1,100 N) and is characterized by its ultra-low release shock (<300 g's @ 250 lbf). NEA® mechanisms were first fielded in 1998 aboard the Intelsat 8 (PAS-8) Geostationary satellite for antenna and solar array release, and have since seen broad industry adoption on LEO, GEO, and scientific missions. EBAD’s NEA® mechanisms have been used on more than 750 spacecraft and have thousands of on-orbit actuations without failure. This mechanism utilizes Non-Explosive Actuator (NEA®) technology for medium-to-high preload applications and offers wide temperature performance. EBAD manufactures thousands of space mechanisms annually, meeting demanding quality requirements and offering robust industrial capacity for high-volume constellation programs. The device has a proof load rating of 300 lbf (1,300 N) and a maximum angular misalignment of 3° Cone.
