The SH-10 laser safety shutter consists of a blade mounted on a rotary solenoid with a limited
rotation angle. When the shutter is powered, the blade moves to an "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 0.01" thick anodized aluminum. To meet laser specifications and for
uses like plasma or X-ray other materials and thickness are used.
THE SHUTTER IS IN THE "CLOSE" POSITION WHEN THERE IS NO CURRENT.

PI= Position indicator to indicate the position of the blade
The SH-10-PI Laser safety shutter incorporates two magnetic switches (sensors) that are a position
indicator to identify the position of the blade.
When the blade is in the "CLOSE" position one of the magnetic switches is normally closed and the
other is normally open. When the blade moves to the "OPEN" position the normally closed switch
becomes normally open and the normally open becomes normally closed. A three pin MOLEX
connector (P/N 22-03-2031) is used for the output of the position indicator.

Damage threshold: The standard blade is 0.01 inch thick black anodized aluminum, which
withstands 100 mW/mm² with a limit of 2 W of total power. We also offer solutions that meet laser
specifications, different wavelengths and more powerful laser beams. We offer a variety of materials
and thicknesses suitable for laser light, X-Ray and plasma, from VIS to FIR applications.
Please call to discuss your specific application.
You can also indicate the most suitable material for your application and supply your own mirrors,
gratings or other attachments.
The standard blade material for the SH-10 is 0.01 inch thick black anodized aluminum.
The standard blade material for the SH-20 is 0.02 inch thick black anodized aluminum.

DRIVERS AND WAYS TO ACTIVATE THE LASER SAFETY SHUTTERS:
You can activate the laser safety shutter by applying the appropriate voltage: 5V to the SH-10-5, 12V
or 15V to the SH-10-12 and 24V to the SH-10-24.
We can supply you with schematics to build your own driver. When ordering a shutter without a
driver, please indicate one of the operating voltages: 5V, 12V or 15V, or 24V.
The DSH-10 DRIVER operates the SH-10 Laser Safety Shutter. The DSH-10 driver includes a three
position control switch. In the "OPEN" position, the shutter is continuously open. In the middle
position, the shutter is continuously closed. In the "TTL" position, an external TTL signal controls the
shutter. A high or open circuit at the TTL input sets the shutter in the closed position. A low or short
to ground at the TTL signal sets the shutter in the open position.
The following driver models that enable the user to control the shutter with a TTL signal
are available:

DSH-10-110 or DSH-10-220, a cased driver 5.3" x 5.3" x 2" operating from a line voltage
of 110Vac or 220Vac (please specify DSH-10-110 or DSH-10-220).

DSH-10-110/220, a cased driver 5.3" x 5.3" x 2" with a selector switch for operating from a
line voltage of 110Vac or 220Vac.

DSH-10-110-BNC or DSH-10-220-BNC, a cased driver 5.3" x 5.3" x 2" operating from a
line voltage of 110Vac or 220Vac (please specify DSH-10-110 or DSH-10-220) with a BNC
connector for TTL input.

DSH-10-5-PC, this is a PC board level driver for the SH-10-5 shutter that needs 5Vdc and
12Vdc (200mA).

DSH-10-TIMER-S, this is a preset timer to open the laser safety shutter for a specific time
from the range of 0.1sec to 10 minutes. Used only with the SH-10-24.

DSH-10-TIMER-L, this is a preset timer to open the laser safety shutter for a specific time
from the range of 0.1min to 10 hours. Used only with the SH-10-24.
