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 P50 model offers a 50 lbf (222 N) pull force and a side load (actuation) of 50 lbf (222 N). It has a non-actuation side load of 400 lbf (1,823 N). The device operates with a current range of 1.25 to 4.5 A and has a resistance of 3.1±0.3 Ω. Its function time at 23ºC is 100 ms max at 4 A. The P50 model is designed for a minimum of 50 cycles and operates within a temperature range of -60ºC to +70ºC. It is front resettable, with rear resettable as an optional feature with growth in the device. 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.
