About
EBAD’s TiNi™ Pin Pullers are non-pyrotechnic separation systems used in satellite applications to provide a simple and effective solution where a pull force is required. The P25 model offers a 25 lbf (111 N) pull force and a side load (actuation) of 20 lbf (89 N). It has a non-actuation side load of 330 lbf (1,468 N). The device operates with a current range of 0.6 to 2 A and has a resistance of 5.8±0.5 Ω. Its function time at 23ºC is 130 ms max at 2 A. The P25 model is designed for a minimum of 100 cycles and operates within a temperature range of -65ºC to +70ºC. It is front/rear resettable. The pin puller utilizes a Shape Memory Alloy (SMA) wire to release a latch, allowing internal compression springs to retract the pin. It features a redundant firing circuit, maximum reliability through design simplicity, and flight pedigree. Applications include solar array and instrument deployment, instrument launch locks, and optic cover releases. The enclosure is typically made with aluminum alloy with a titanium flange, and the output pin is stainless steel with a tiolon finish.
