The NK-R102NC X-ray collimator from Newheek is a manual beam-limiting device specially designed for mobile X-ray machines. It pairs with X-ray tubes rated up to 150kV, helping operators precisely control the X-ray radiation field, reduce scatter radiation, and protect patients and staff from unnecessary radiation exposure.
The NK-R102NC collimator is mainly applied on mobile X-ray equipment. It matches X-ray tubes with a maximum tube voltage of 150KV, widely used for clinical mobile radiographic examinations.

Product Features
This collimator adopts manual continuous adjustable lead shutters. Operators can easily adjust the radiation field size to match the imaging area, limiting X-ray beam coverage only to the target region.
It comes with a built-in LED localizing light. The light simulates the X-ray field for fast positioning. The lighting timer can be adjusted between 30s and 60s, saving power and extending LED service life.
Multiple aluminum filter plates are pre-installed inside. Users can select 0, 0.5,1.0 or1.5mm AL filters according to examination needs. The filters remove low-energy X-rays, lower patient radiation dose and improve image quality.
The rotation locking structure uses flange and press plate locking, stable and reliable during mobile X-ray movement. A 2-meter SID measuring tape is integrated for quick source-to-image distance reading at bedside or field sites.
Working & Safety Value
Controlling the X-ray beam by collimator is essential in radiography. By narrowing the radiation field, the NK-R102NC cuts down scattered radiation. Less scatter means higher image contrast, while also reducing radiation exposure outside the area of interest.
It is built for mobile X-ray units, which often work in non-fixed shielding rooms. Proper collimation becomes even more important for radiation protection during bedside or on-location radiography.
Summary
The NK-R102NC X-ray collimator is a robust manual collimator for 150kV mobile X-ray systems. With adjustable lead shutters, LED positioning lamp and interchangeable aluminum filters, it delivers accurate beam control. It balances reliable imaging performance and radiation safety, a practical accessory for mobile digital radiography machines.
