Description
Product Description
- Blade-type optoelectronic shutter with millisecondlevel operation.
- SM05 (0.535″-40) threaded aperture, compatible with SM05 lens tubes.
- Closing response time: 10 ms typical (20%–80% exposure) with OBS-C1 controller.
- Default state: closed.
- Compatible with OBS-C1 controller (sold separately).
The bladetype optoelectronic shutter provides millisecondlevel operation, ideal for blocking/unblocking laser beams.

Definitions
- TI (Transfer Initialization): Time from voltage application to initial shutter movement.
- TO (Transfer Open): Time from 20% to 80% exposure, measured over 1/2inch travel.
- TD/R (Transfer Dwell/Release): Time from voltage/pulse removal to shutter closing start.
- TC (Transfer Close): Time from 80% to 20% exposure during closing.
- MSOP* (Minimum Shutter Opening Time): Minimum open time using MOP from OBS-C1.
- MOP (Minimum Open Pulse): Minimum pulse width of OBS-C1 controller.
OBS-C1 Optoelectronic Shutter Controller
The OBS-C1 drives and controls one channel of optoelectronic shutter or other solenoid devices. It works with Oeabt OBS-P1 and compatible current/pulsedriven actuators.

Technical Notes
The OBS-P1 features an SM05 threaded aperture with a swinging blade, enabling millisecondlevel operation. It remains closed by default and opens only when a control pulse is received. Speed and frequency are adjustable via the OBS-C1 controller (sold separately).
The OBS-C1 controller drives and controls one channel of optoelectronic shutter or solenoid devices. A toggle switch powers the controller on/off. It connects to the OBS-P1 and other compatible actuators.
Controller Main Menu (full manual available upon request):
- Mode: Manual, Auto, External Trigger
- Shutter Settings: Set on/off durations in 100 ms steps (multiples of minimum duration)
- Display: Adjust brightness and sleep timeout
The shutter stays open if the control voltage is maintained above the threshold; it closes when voltage drops below the threshold.
Multiple units can be linked via trigger I/O for synchronized or asynchronous multi-channel operation.
