NK-RM301-E Electric X-Ray Beam Collimator for 150KV X-ray Tube
Short Description:
The NK-RM301-E electric X-ray collimator from Newheek is a precision beam-limiting accessory, specially designed to match X-ray tubes with a maximum voltage up to 150KV. It controls the X-ray irradiation field accurately, restricts redundant radiation output, lowers unnecessary patient exposure and helps radiographers get stable diagnostic images. Built with reliable electric lead leaf control and multi-layer shielding blades, this collimator is widely adopted in fixed radiographic rooms and integrated DR systems.
This collimator adopts a three-layer blade structure plus protective tube design. The lead leaves are driven electrically, instead of manual adjustment, which supports automatic control operation. The built-in LED light locates the exposure field visually, helping technicians align the shooting area before radiation release. An SID measuring tape is supplied as standard equipment for fast distance confirmation during daily radiography work.
Irradiation Field Range
At the standard SID of 100 cm, the maximum irradiation field reaches 480+10 × 480+10 mm². The minimum irradiation field can be smaller than 50 mm × 50 mm. The wide adjustable range can fit various clinical shooting demands, from small local parts to large-area torso radiography. Operators can shrink the beam strictly to the target region to cut down scattered rays effectively.
Light Field and Filtration Specification
It is fitted with an SST-50 LED lamp, rated at 24V and 20W. The lighting delay time of the light bulb is 30s ±5%. The inherent filtration of this collimator is 1mm Al, which meets common diagnostic radiographic filtration requirements and balances beam quality and radiation dose well.
Electrical and Mechanical Parameters
Max supported X-ray tube voltage: 150KV
Distance from focus to collimator mounting surface: 60 mm
Power supply: 24V AC/DC (±5%)
Overall dimension: 250 × 215 × 210 mm (L × W × H)
Net weight: 9.2 ±0.5 kg
The compact cabinet structure is convenient for installation on standard X-ray tube assemblies. The 24V wide-range power input ensures stable performance for most medical radiographic systems.
Application Scenarios
The NK-RM301-E electric collimator is matched for 150KV X-ray generators in medical diagnostic radiography. It works together with DR systems, stationary X-ray tables and vertical bucky stands. With electric lead leaf control, it suits busy imaging departments that need fast, repeatable collimation settings. It also supports pairing with grids and detectors for standard human radiography examinations.
Summary
The NK-RM301-E electric X-ray collimator delivers precise beam control, stable LED light field indication and solid multi-layer radiation shielding. Its 150KV rating, wide adjustable irradiation field and electric drive mode make it a practical upgrade choice for medical X-ray systems. It helps facilities comply with radiation safety rules while maintaining consistent diagnostic image quality.
