A leading U.S. defense contractor required specialized door solutions for active testing booths within their production facility — an environment where personnel safety and system reliability are non-negotiable.

Full-vision panels were specified to maintain complete sightlines into the testing area at all times, while the door control system required a positive-signal "hold closed" interlock to prevent inadvertent opening during live testing sequences. Critically, the controls integration was engineered to meet Performance Level d (PL d) per ISO 13849 — one of the highest machine safety integrity ratings — ensuring the doors functioned as an active safety element within the customer's broader facility control architecture.

Newport supplied multiple doors and executed significant controls modifications and custom integration work, delivering a solution that operated seamlessly within the customer's existing safety and automation systems.
