Goldantell Electrostatic Discharge (ESD) Testing TurnstileIntroduction and Description
Goldantell ESD testing turnstile is an integrated access control system designed to ensure personnel entering sensitive electrostatic discharge (ESD)-protected areas (EPAs) meet predefined static control requirements. It combines physical barriers (turnstiles or gates) with embedded ESD testing technology to enforce compliance with ESD safety protocols, commonly used in electronics manufacturing, laboratories, cleanrooms, and data centers.
Key Components and Features
1. ESD Testing Unit
- Equipped with conductive plates or sensors to measure the electrical resistance of a person’s body (typically hand-to-foot resistance).
- Verifies if the individual is properly grounded via wrist straps, footwear, or other ESD-safe equipment.
- Thresholds are set according to industry standards (e.g., ANSI/ESD S20.20: resistance ≤ 35 megohms).
2. Access Control Mechanism
- Turnstile/Gate: Physical barrier (optical, tripod, or full-height) that unlocks only upon successful ESD testing.
- LED Indicators: Visual alerts (green/red lights) to signal pass/fail status.
- Audible Alarms: Alerts for failed tests or unauthorized access attempts.
3. Integration Capabilities
- Connects to access control systems (e.g., RFID card readers, biometric scanners) for identity verification.
- Logs data (time, user ID, test results) for compliance audits.

Operation Workflow
1. User Approach: Employee steps onto the ESD test plate or grasps hand-contact sensors.
2. Resistance Measurement: System checks if body resistance meets safe thresholds.
3. Access Decision:
- Pass: Turnstile unlocks, granting entry.
- Fail: Barrier remains locked; alerts prompt corrective actions (e.g., rechecking wrist straps).

Applications
- Electronics Manufacturing: Prevents static damage to components (e.g., semiconductors, PCBs).
- Pharmaceuticals/Cleanrooms: Ensures static control in environments sensitive to particulate contamination.
- Data Centers: Protects servers and storage systems from ESD-induced failures.
Compliance and Safety Standards
- Aligns with ANSI/ESD S20.20, IEC 61340, or facility-specific ESD control programs.
- Regular calibration ensures measurement accuracy.
Maintenance and Calibration
- Routine cleaning of sensors to prevent false readings.
- Periodic recalibration using certified resistance testers.
Advantages
Risk Mitigation: Reduces ESD-related product defects or equipment damage.
Efficiency: Automated testing streamlines entry processes.
Audit-Ready: Digital logs support compliance reporting.
By integrating ESD testing with physical access control, these systems enforce static safety protocols while maintaining workflow efficiency in critical environments.
