Product description
swing freely. The AFB slightly dampens the free swing, thereby making a close approximation of the forearm's
physiological movement behaviour possible.
The product does not consume electrical energy during the free swing. A short muscle signal to flex the product
ends the free swing.
Humeral rotation feature
The humeral rotation feature is an upper arm rotation joint with bilateral stops. It is used for rotation of the forearm.
The resistance of the humeral rotation feature can be changed using the adjusting screw.
Easy Plug
The Easy Plug feature makes it simple to wire myoelectric prostheses.
The connecting cables of the electrodes and an optional switch are connected to the Easy Plug. Its interior cable
routing minimises the risk of cable breaks.
Forearm cable
INFORMATION
Do not pull out cables before cutting the forearm to length.
Lock
Releasing and locking the elbow joint is automated according to operating situations, the applied load and the con­
trol signal generated by the patient by means of the electronically controlled locking drive.
The product has a load capacity of up to 230 N in the locked state with a forearm lever length of 305 mm. The lock
will slip under higher loads.
Mechanical release
With the product switched off or when the battery is drained, the elbow can be manually unlocked and locked
again with a slight pull on the unlock cable. In this way, the forearm can be brought into the desired position.
Mechanical release can also take place under load.
