XRpad 4336 Wireless a-Si X-Ray Detector
The PerkinElmer XRpadTM 4336 is a wireless, light weight, cassette-sized flat panel detector for digital radiography.


The PerkinElmer XRpadTM 4336 is a wireless, light weight, cassette-sized flat panel detector for digital radiography. It fits into a conventional table or wall-stand Bucky, just like a film-screen cassette.

Featuring a 15 million pixel image matrix, a best-in-class 100 μm pixel pitch, and a directly deposited CsI scintillator, the PerkinElmer XRpadTM 4336 provides exceptional image quality. True 35 × 43 cm2 imaging area per the ISO 4090 cassette standard is provided, along with a removable, rechargeable battery. Single-piece carbon-fiber construction for the front and back housing allows for easier placement and cleaning. Automatic Exposure Detection simplifies integration.

We have over 20 years of experience partnering with customers to develop products in a wide range of X-ray applications. Let our digital imaging experience work for you.
