Balloon Cutdown

This cutdown can satisfy the alternate termination requirement for high altitude balloon experiments. The cutdown mechanism arms after it detects ascent of the balloon and will disarm if the flight naturally terminates to prevent on the ground cutdown. Flights can be terminated based on pressure or time. Paired with our balloon satellite tracker system and XBee Radios, a remote cutdown command can also be initiated. A hot nichrome wire (not included) is used in an easily replaceable terminal block to melt train lines and separate the payload from the balloon.

Balloon Cutdown Enclosure

This light-weight enclosure for our balloon cutdown mechanism keeps the circuit board dry and protected while allowing smooth separation of the payload and balloon. Add one of our pull pin switches to your cart and we can pre-mount it in the bottom of the enclosure for an easy "pull before flight" style activation.

XBee Radio - Cutdown Programmed

XBee radio programmed to work with our cutdown/satellite tracker system for high altitude balloon projects. Our team will contact you to arrange the network settings and passcodes as you wish. These radios are for short range communications between a instrument package mounted tracker and balloon train cutdown device, not for ground to sky communication.

NOTICE: These products are currently out of stock due to supply chain issues with no current estimated restock date. Alternative radios from Digi are also currently unavailable. As soon as this unit or a suitable replacement is back on the market we will update this product page.
