Product catalog summary
Explosion Proof Solenoids and Sensors Overview

Introduction
This document provides an overview of explosion-proof solenoids and sensors, highlighting their use in hazardous environments such as oil and gas extraction, mining, and areas with gas and dust atmospheres.

Certification Schemes
  • Local Certification: Products must be tested by a Nationally Recognized Testing Laboratory (NRTL) in the USA, following the National Electrical Code (NEC).
  • Global Certification: The IECEx certificate is widely accepted for local certification in many countries, though acceptance varies.
  • Regional Variations: Specific requirements exist in different regions, such as ATEX in Europe and TR-ZU in Russia, often aligned with IEC standards.

Challenges and Considerations
Not all IECEx member countries recognize its certificates automatically. Australia and New Zealand accept IECEx without additional conditions, while the USA and Canada have unique classification systems.

Product Specifications
  • Twin Solenoids: Certified under ATEX, operating within -35°C to +40°C, suitable for gas and dust atmospheres.
  • Electrical Data: Nominal voltage is 24V DC with a limiting current of 0.63A.

Conclusion
Schienle Magnettechnik offers extensive experience in explosion protection, providing globally approved products and assisting in developing products for international compliance.

Technical Specifications and Certifications
  • Electrical Data: Nominal voltages range from 12V to 205V, with varying limiting currents and power-on times.
  • Mechanical Data: Solenoids have a working pressure up to 50 bar, with strokes typically at 1.2 mm, manual override, and zinc plating for surface protection.
  • Environmental Conditions: Ambient temperatures range from -40°C to +70°C, with maximum medium temperatures up to +70°C.

Certifications
  • ATEX, IECEx, NEC, and other regional certifications ensure compliance with safety standards for explosive environments.
  • Protection classes are generally IP67, with isolation class H for coils.

Product Variants
  • Twin Solenoids: Various models with specific certifications and labeling for different regions and applications.
  • Single Stroke Solenoids: Models with pressure-tight tubes and varying force and stroke characteristics.

Key Features
  • Flame-proof and intrinsically safe designs for hazardous locations.
  • RoHS compliance and robust surface protection for durability.
  • Zero gas volume devices with waterproof coil and gland areas.

Actuator Systems and Displacement Transducers
  • Single Stroke Solenoids: Operate at 12-205 V DC, with pressure-tight tubes and certifications including ANZEx and RoHS compliance.
  • Displacement Transducers: Certified under ATEX and IECEx, featuring intrinsic safety with Zener Barriers.

Certification and Safety Standards
Devices are certified under various international standards, ensuring compliance with safety and operational requirements in hazardous environments. Protection classes range from IP65 to IP67.

Electrical and Mechanical Specifications
Nominal voltages range from 6 V to 230 V, with varying current limits and power-on times. Mechanical features include tube diameters, working pressures, and surface protection standards.

Conclusion
The document provides comprehensive technical details and certifications for actuator systems and displacement transducers, emphasizing their suitability for hazardous environments with stringent safety and performance standards.

IECEx Türöffner zu regionalen Märkten Aufgrund des Gefährdungspotenzials für Mensch und Umwelt bestehen im Zusammenhang mit Explosionsschutz eine Vielzahl gesetzlicher als auch vergleichbarer Regelungen mit nationaler Prägung. Solche nationalen Einflüsse führen dazu, dass Produkte welche zum Beispiel den Europäischen Anforderungen entsprechen in außereuropäischen Ländern nicht oder nur mit zusätzlichen Prüfungen oder Dokumenten einsetzbar sind. Im europäischen Raum wird das ATEX Zertifikat in den 28 Mitgliedsstaaten der EU und den 4 Mitgliedsstaaten der EFTA (Island, Lichtenstein, Norwegen, Schweiz)...

Leider bedeutet die Mitgliedschaft nicht gleichzeitig die nationale Anerkennung von IECEx-Zertifikaten. Lediglich der IECEx-Vorreiter Australien sowie Neuseeland erkennen IECEx-Zertifikate ohne zusätzliche Bedingungen an. Aber selbst hier existieren im Bereich des Untertagebaus national geprägte Restriktionen. Wer solche Spezifika nicht kennt, setzt unter Umständen auf das falsche Zertifikat. Unserer Erfahrung nach ist der Weg zu einem weltweit anerkannten Zertifikat mit dem IECEx-Scheme zwar beschritten worden, ob dieses Ziel jemals vollumfänglich erreicht wird ist jedoch ungewiss. Und doch...

Nationale Besonderheiten als Herausforderung In den USA hingegen steht die Division-Einteilung weiterhin gleichwertig neben der Zonen-Einteilung. Allerdings gibt es eine klare Entweder-oder-Entscheidung. Auch für bestehende Anlagen besteht eine Re-Klassifizierungs­ option, welche aber aufgrund der wirtschaftlichen Konsequenzen eher theoretischer Natur ist. Es gibt eine Vielzahl solcher oder ähnlicher nationaler Besonderheiten die den Einsatz von Geräten in explosionsgefährdeten Umgebungen regeln.
