XRS25 25mm Uni-Stable Shutter SpecificationsFeatures






The UNIBLITZ® XRS25 is especially designed for x-ray applications.

Non-resonant design allows instantaneous changes of the repetition rateand duty cycle.



No optical surface when open provides 100% transmittance.

Can open within 10.0msec at a maximum rate of 10Hz
Pt-Ir shutter blade, capable of blocking x-ray energy 30Kev.
Exposure repetition rate continuously variable from DC to 10Hz.
Electronic synchronization system available.
Activated by an electronic pulse through UNIBLITZ® patented shutter
drive systems.

Available in a normally-open configuration.
This device will require two drive channels for operation and a speciallymodified cable (the 910C-D7) is required to connect to the driver (thiscable is included).

The Electronic Synchronization System provides a feedback signal(through the driver utilized) after the shutter transfers to the openstate. The system incorporates dual syncs – one for each blade – andare operated in a wired AND configuration to insure that the output
will not change state unless both blades have opened. Each sync system is comprised of an infrared emitting diode, an infrared sensitive
detecting transistor, and an interrupting vane. The vane is attached toeach shutter blade so as to block the light path between the emitterand detector in the closed position. When the shutter transfers to the80% open position, the associated vanes are removed from the infrared light paths, allowing the emitters of each of the syncs to switch
the detectors to the active state. No connection to the designatedsynchronization pins when no electronic sync is selected.

Cable Adapter

IncludedFig. 4* If the added cable length using the 710A cables isundesirable, the 910C-D7 can be equipped withdual 5-pin male Switchcraft connectors in place ofthe standard 7-pin connectors for direct connection
to the VCM type controllers. This cable is referred toas 910C-D5 and only available on special order.
Please contact a technical representative for
additional information.

Fig. 4 illustrates 910C-D7 Cable required to allow proper connection of the XRS25 to VCM/VMM type controllers. The dual 7-pin
male connectors of the 910C-D7 Cable would connect to the VCM controllers (through the 710A*) or VMM controllers directly and the9-pin female would connect to the shutter as illustrated in figure #3.

Fig. 7NOTE:
The cable required is nonstandard, the 910C-D7 (9-pin
female connector to dual 7-pin
male connectors, 10ft. inlength). This shutter device
requires two driver channels forproper operation and each ofthe 7-pin connectors of the910C-D7 would be connectedto the SHUTTER output of twoseparate VMM type driverchannels. The drive channels
should be triggered simultaneously to achieve published typical timing specifications.
