ErgoArm Electronic plus

Item #: 12K50

Log in to order

The 12K50 ErgoArm Electronic plus is a lightweight and versatile electronic locking elbow that is compatible with a myolectric hand or terminal device.

Features include:

The internal Infinite Position lock is cable-operated and can be locked, or unlocked, under load in any position. It can bear a load of up to 230N at a forearm length of 305mm.

The Slip-Stop function makes it possible to lower the forearm in a controlled manner without having to fully release and reactivate the lock. In the ErgoArm Electronic plus, this feature is electronic versus mechanical.

Automatic Forearm Balance (AFB) supports flexion by using energy stored during extension. It promotes a smoother motion when swinging the arm, making it easier to lift the arm. For improved cosmesis, the AFB finger wheel is now the same color as the forearm shell.

Easy Plug allows the electrode and battery connecting cables to be plugged into the elbow cover. Internal cables enhance overall cosmetic appearance while also increasing durability.

Electronic Lock enables the user to control the elbow’s locking and unlocking with myoelectric signals (2 electrodes: co-contraction) or by means of a switch. Eight switching modes are available which permits customization of the lock control system to the user’s personal requirements.

A new membrane cover in the crook of the arm protects internal components and prevents user’s clothing from potentially getting trapped, enhancing overall appearance and functionality.

Please see the ErgoArm Family Selection Guide for available sizes and corresponding color options.
