The SH-10 consists of a blade mounted on a rotary solenoid with a limited rotation angle. The SH-20 shutter consists of blades mounted on rotary solenoids. When the shutter is powered, the blade moves to the "ON" position and clears the path for the laser beam. When the power is turned off, the return spring of the shutter moves the blade to the "OFF" position and blocks the laser beam. The standard blade material is 0.1" thick anodized aluminum; to meet laser specifications, other materials or thickness are available.

Configurations:

Models SH-10-M and SH-20-M shutters come with a mounting plate option and allows horizontal and vertical mounting. Model SH-10-L and SH-20-L shutters offer long life operation: 50 million cycles minimum. Model SH-10-B and SH-20-B shutters are boxed with a window for laser light. Model SH-10-M-L and SH-20-M-L shutters come with a mounting plate and allows horizontal and vertical mounting and offers long life operation: 50 million cycles minimum. SH-10-5 and SH-20-5 for 5V power requirements, SH-10-12 and SH-20-12 for 12V or 15V, and SH-10-24 and SH-20-24 for 24V operation.
