EOPC has introduced its new low cost, long life Laser Safety Interlock Shutter. The shutter consists of a blade mounted on a rotary solenoid with a limited rotation angle. When the shutter is powered, the blade moves to the 'on' position and clears the path for a laser beam. When the power is turned off, the return spring of the shutter moves the blade to an 'off' position and blocks the laser beam. The standard blade material is black anodised aluminium; to meet laser specifications, other materials and thickness are available.
The device features 0.5-inch and 1-inch apertures, 5V, 12V or 24V DC operation, a simple drive circuit for TTL input, and compliance with RoHS.
