The UL‑SP Series pneumatic shielded enclosures deliver automated, repeatable RF isolation across 700 MHz–6 GHz, featuring a wide range of internal sizes (from 300×300×300 mm up to 500×500×400 mm) and customizable filter interfaces (SMA, BNC, DB9/25, USB, RJ45, DC, AC, etc.). Ideal for high‑throughput production line calibration, coupling tests, and R&D verification.
UL‑SP Series Pneumatic RF Shielded Enclosures – Efficient, Automated Testing for High‑Volume Production
The UL‑SP Series is a comprehensive family of pneumatically operated shielding boxes engineered to streamline wireless testing in both production and laboratory environments. Covering a broad frequency range from 700 MHz to 6 GHz, these enclosures effectively suppress external electromagnetic interference (EMI) and cross‑coupling, ensuring precise and consistent RF calibration, sensitivity measurements, and transmitter adjustments – even in noisy factory floors.
Pneumatic operation is the key differentiator of this series. With a simple air‑pressure control, the lid opens and closes automatically, enabling fast, repeatable, and hands‑free testing cycles. This significantly boosts throughput and reduces operator fatigue, making the UL‑SP Series an ideal choice for high‑volume manufacturing lines where speed and reliability are critical.
The series offers eight distinct size configurations to accommodate a wide variety of Devices Under Test (DUT) – from compact modules (internal 300×300×300 mm) to larger boards (500×500×400 mm). Several models feature split‑cavity designs (upper and lower compartments) for specialized test setups, providing extra flexibility for complex DUT geometries.
Customization is at the heart of the UL‑SP Series. The interface filter panel can be tailored to your exact needs – standard options include SMA (2/4 ports), BNC, DB9, DB25, USB 2.0, DC power, RJ45 Ethernet, and even AC220V input. This ensures seamless integration with your existing test instruments, signal generators, power supplies, and control systems without additional adapters.
Built with robust sheet‑metal construction and reliable pneumatic components, these enclosures operate consistently across a wide temperature range (0 ~ 50 °C). Whether you are performing conducted or radiated testing, the UL‑SP Series delivers stable shielding performance, helping you minimize false failures, avoid costly re‑tests, and maintain high quality standards throughout production.
Choose the model that fits your DUT size, interface requirements, and automation needs – and boost your test efficiency today.
