The dependable NS Shutter Series has been increased with the introduction of the 65 mm aperture NS65B - the largest aperture in the NS series.

Boasting only a total of seven moving parts, six of which are the blades themselves, has significantly enhanced the reliability of the NS6.

Being a bi-stable shutter means that no power is required to hold the shutter in either the open or closed state and only when a change of state is required is it necessary to use power. By reducing the number of components and utilizing the bi-stable operation has allowed for a more reliable and dependable device.

The NS65B can fit into a 12.7 cm (5") diameter housing and can be operated by the VDM1000 controller.
