High EMI resistance accelerometers HV100 and HV200 series Wilcoxons HV series are designed for demanding applications requiring high electrical isolation between the sensor and machine. HV sensors can withstand arcing between the sensor base and its internal electronics to levels as high as 6,000 volts. The sensors offer improved EMI resistance in areas where high electromagnetic interference occurs, such as wind turbines, railway systems and other high-voltage generators. Improvements in EFT and ESD resistance improve survivability during extreme transient events. The HV series are available with a variety of mounting options to ensure compatibility with every application. Key features Case-base isolated up to Models available 6 kV HV models Output connector Integral mounting Ideal for power generation HV100 M8 x 1.25 applications HV101 4 pin, M12 1/4-28 UNF Rapid shock recovery HV102 M6 HV200 1/4-28 UNF Improved EMI resistance HV201 2 pin, MIL-5015 M8 x 1.25 Manufactured in an HV202 M6 approved ISO 9001 facility Certifications Note: Due to continuous process improvement, specifications are subject to change without notice.
