NS15B 15mm Bi-stable Shutters

Overview
The NS15B is the smallest NS standard devicepresently available. The device’s reliability has been enhancedby
significantly reducing the number of moving parts. In the15mm aperture version, the NS15B, has a total number of
sixmoving parts, five of which are the blades themselves! Theactivating mechanism is non-contact and has shown to
increaseits reliability through testing over similar shutter designs. Bi-stableversion is standard and uni-stable is
available by specialorder. The N-CAS shutter system has demonstrated to be themost reliable shutter device of its type
available on the markettoday!

FEATURES
• All new N-CAS actuator system radically reduces moving parts.
• Bi-stable configuration is standard.
• Simple design provides maximum clearance around the aperture.
• Smallest aperture NS device presently available.
• Machined flat surfaces for easy integration into virtually any system.
• Small form factor, 15mm aperture, 1.40 inch overall diameter.
• Reflective blades available.
• Terminated to 6 inch 2-pin male connecter harness for direct connection to the ED12DSS.
• Can be connected to the VDM1000 using the included 501A-J2 adapters
