ARQUIMEA’s REACT devices are low-shock Hold-Down & Release Actuators
which function is to firmly fix a payload during transportation or launch and
later release it by electrical activation. REACT implements a redundant trigger
with two different motorization options based on Shape Memory Alloys (TiNi
and SMARQ®) covering wide actuation temperature ranges and providing
manual reset capability to the end user.
Typical applications of REACT include: solar arrays, antennas, booms and
masts, reflectors, cover doors, scientific instruments, shutter mechanisms, large
structures, launch locks for gimbals, thrusters, stage separation, caging
mechanisms, etc.
