Voltage to Open+70 VDChousing. The CS45 is available in a housed or an un-Hold Voltage (Nominal) 1+7 VDC / +5 VDC 2more. The slim form-factor provides a 45mm aperturehoused configuration for OEM applications (or simply
where spatial limitations are a consideration).
Mechanical Specifications

Uni-stable shutter devices, like the CS45, require
power to hold the blades in the open state.

Under no circumstances should any type of lubricant be applied tothe shutter blade area. Lubricating the shutter blades will likely slow
the shutter down and may eventually render it inoperable.
