Model 4901Photon Pin IonizerThe Model 4901 Photon Pin Ionizer is designed to eliminate static charge in semiconductor and other ultra-clean manufacturing processes where fast discharge time, low swing voltages and precision balance are required. 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 amount of positive and negative ions. Charged objects in the proximity of these positive and negative ions attract the opposite polarity ions to them neutralizing the charge on the object. Photon ionization is an advanced and essential solution for effective ESD, ESA, and ESC control.The Model 4901 Photon Pin Ionizer designed with a convenient all-inone, integrated head system accommodates narrow, confined space and in-tool applications.%u2022 Suitable for critical cleanliness control%u2022 Low voltage tube type (exemption of safety licensing)%u2022 Pin-type designed for narrow, confined space and in-tool applications%u2022 Alarm output signal%u2022 Perfect ion balance%u2014the same amount of both positive and negative ions are generated when a molecule is exposed by soft X-ray%u2019s energy; thus, Photon ionizers are inherently free from ion balance issue%u2022 Free from particle attraction%u2014Photon ionizers does not require air supply (i.e., CDA) but utilizes a source of Soft X-ray, no contamination particles are generated%u2022 No maintenance is required%u2014unlike conventional ionizers of corona discharge on emitter tips, Photon ionizers do not need any cleaning or ion balance tuning during its lifetimeFeaturesBenefitsDischarge Time Performance 4901 SpecificationsPower Input 24 VDC, 60WDischarge <1 sec @ 6%u201d (15.2 cm); %u00b11,000V to %u00b1100VBalance Inherently balanced 0VIon Emission Soft X-ray TechnologyEmitterPhoton generating tube with beam angle 150%u00b0 in tube typeType: Hot filamentVoltage: 4.98 kVCurrent: 400 %u03bcA (max), on-site receptacleCleanroom Class Zero particle generationLED Indicator Run, Lifetime, AlarmAlarm Head Fail, System FailOperating Env 32-122%u00b0F (0 to +50%u00baC); 35-85% RH, non-condensingDimension Pin Head: 0.94%u201d dia. x 3.35%u201dL (2.40 x 8.50 cm)Ionizer: 3.3%u201d x 1.3%u201d x 4.8%u201dL (8.38 x 3.40 x 12.4 cm) with bracketWeight 0.875 lb (0.40 kg)Certification UL pending63 Sales Service +1 (510) 217-0460 or +1 (800) 367-2452 www.simco-ion.com/technology Special Application Ionizers
