Model 4901

 

      

 

The Ultimate All-in-One Advanced Photon Ionization for any Ultra-clean Process

The Model 4901 Photon Pin Ionizer is designed to eliminate static charge in semiconductor and other ultra-clean manufacturing processes requiring fast discharge time, low swing voltages, and precision balance. Model 4901 utilizes a soft X-ray source, a form of light, and does not require an air supply to deliver ionized molecules. 

Soft X-rays are easily absorbed by the atmosphere, generating an equal number of positive and negative ions. Charged objects in the proximity of these positive and negative ions attract the opposite polarity ions, neutralizing the charge on the object. Photon ionization is an advanced and essential solution for effective ESD, ESA, and contamination control. 

  • Suitable for critical cleanliness control
  • Low voltage tube type
  • Pin-type designed for narrow, confined space, and in-tool applications
  • Alarm output signal
