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.
