ESD Simulators

ESD (electrostatic discharge) simulators, also known as ESD guns or ESD immunity testers, are instruments used to evaluate the robustness of electronic products against electrostatic discharge events as defined in IEC 61000-4-2 and related standards. They generate precisely controlled high-voltage, fast-rise-time discharge pulses that replicate the discharge a person or conductive object might deliver to electronic equipment through contact or air discharge. ESD immunity testing is a mandatory requirement for most consumer, industrial, and professional electronic products entering regulated markets worldwide.

Modern ESD simulators often form part of larger multi-function immunity test platforms alongside electrical fast transient (EFT), surge, and voltage dip generators. Compact integrated platforms from manufacturers such as Haefely and Emtest allow laboratories to perform a broad range of IEC 61000-4 immunity tests from a single instrument, reducing setup time, calibration overhead, and laboratory floor space requirements.

Typical Applications

ESD immunity testing per IEC 61000-4-2 for consumer electronics, industrial, and medical equipment
Contact and air discharge testing on enclosures, connectors, keyboards, and user interfaces
Automotive ESD testing per ISO 10605 for in-vehicle electronic systems and modules
Military and aerospace ESD immunity qualification in defense product development
Pre-compliance ESD testing during product design and design verification stages
