LASER SAFETY (Interlock) SHUTTERS / X-RAY SHUTTERS:

DESCRIPTION:
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 the 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 SHUTTER IS IN THE "CLOSE" POSITION WHEN THERE IS NO CURRENT.
The standard blade material is 0.01" thick anodized aluminum. To meet laser specifications and for other uses like X-ray other materials and thickness are used.

Shutters are stock items.
Shutters are RoHS compliant.
The SH-20 laser safety shutter consists of two SH-10 laser safety shutters based on a single mount going the opposite directions to make a large aperture.

SPECIFICATIONS for the standard SH-10 laser safety shutter:
APERTURE SIZE: 0.5 inch dia; 0.42 inch dia for the boxed version.

M= Mount
MP= Mounting plate (to optical table)
L= Long life (50 million cycles min.)
B= The shutter is boxed, with a cutout for laser light
PI= Position indicator to verify the status of the shutter (open or close)

SH-10-MP

The SH-10-PI Laser safety shutter incorporates two magnetic switches (sensors) that are position indicators to indicate the position of the blade to verify the status of the shutter (open or close).
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.

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.
If you opt not to use our drivers, we supply you with schematics to build your own driver. Please click on "CAD DRAWINGS" for details.
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.
The DSH-10-5-PC, this is a PC board level driver for the SH-10-5 shutter that needs 5Vdc and 12Vdc (200mA).
The 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.
The 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.

The DSH-20 driver can drive two SH-10 shutters simultaneously, open and close both shutters at the same time.
The following models of this driver are available:
DSH-20-110 or DSH-20-220. This is a cased driver 5.3" x 5.3" x 2" operating from a line voltage of 110Vac or 220Vac (please specify DSH-20-110 or DSH-20-220).
