4 Blades Thermal Imaging Shutter Solenoid Driven 21 X 17mm Thermal Camera Accessories

• High Torque Metal Housing:​ With dimensions of 32×32×4.8mm, this model features a slightly thicker profile compared to the 3.8mm version. The metal casing​ not only provides excellent rigidity but also offers superior electromagnetic shielding (EMC), making it suitable for harsh electrical environments.

• Large Aperture Coverage:​ The shutter covers an area of 21×17mm, which is significantly larger than the previous models (13×11mm and 13.5×11.3mm). This indicates it is designed to accommodate larger thermal sensor arrays​ or lenses, providing a wider field of view or higher resolution support.

• Precision 4-Blade PET Design:​ Utilizes 4 PET blades for uniform obscuration. The large size ensures effective blocking of stray light and supports high-quality Non-Uniformity Correction (NUC) for advanced thermal imaging.

• FPC Flexible Cable Connection: Built-in flexible flat cable interface, easy wiring layout inside thermal core, saves assembly space and avoids hard wiring stress fracture.

Application Scenarios

• High-Resolution Handheld Thermal Imagers:​ The large 21×17mm aperture makes it perfect for mid-to-high range thermal cameras used in predictive maintenance, electrical inspections, and building diagnostics, where larger microbolometer arrays are common.

• Industrial &Security Monitoring Systems:​ The robust metal body and 4.0V drive are ideal for fixed-mount thermal security cameras or drone payloads that require high reliability and resistance to vibration.

• OEM Thermal Imaging Modules:​ Suitable for system integrators looking for a shutter mechanism that can handle larger sensors without compromising on NUC accuracy, especially in applications requiring EMC shielding.

• Advanced Night Vision Optics:​ Can be integrated into high-performance night vision monoculars or devices (if permissible by policy; alternatively use "night vision devices"​ or "observation systems") for tactical​, law enforcement, or outdoor activities.
