YX0501 Flameproof Buttons Switches & Operating Heads

Technical Data

1.Explosion-proof Type

• Standards Implemented:YX0501 series push-buttons and switch operating heads are internal components for explosion-proof enclosures without separate Ex certificates, and they must be installed inside enclosures complying with GB3836 for explosive atmospheres.
• Applicable Hazardous Areas: These operating heads cannot be used bare in explosive hazardous areas. They can be applied to relevant gas and dust hazardous zones only after being assembled within certified explosion-proof enclosures.
• Ex Marking: Gas protection: The operating heads have no independent Ex rating. The explosion-proof grade of the complete set is determined by the matched explosion-proof enclosure.

2.Product Parameters

• Product Type: Built-in operating heads for explosion-proof enclosures, including standard push-buttons, emergency-stop buttons, illuminated push-buttons, key-operated buttons and rotary switches for control-circuit operation.
• Certification: No separate Ex certification. They are internal components and shall be used together with certified explosion-proof enclosures.
• Material: Housing options of engineering plastic or metal; insulating base and metal internal contacts; illuminated versions with transparent lamp cover.
• Exposed Fasteners: No exposed fasteners, fixed by clip-in locking through panel cut-out.
• Electrical-Rated Voltage: Illuminated push-buttons support 24VDC, 240VAC. Operating heads adapt to general low-voltage control circuits.
• Electrical-Rated Current: No separate rated current on datasheet, subject to matched contact modules.
• Protection-Ingress Protection: No independent IP rating for operating heads. Protection class depends on complete explosion-proof enclosure.
• Protection-Ambient Temperature: No separate data shown, operating condition follows matched explosion-proof enclosure.
• Connection-Cable Cross-section: Screw-clamp terminals on contact modules for general control cables, no exact wire size specified in datasheet.
• Connection-Cable Entry: No cable entry on operating heads. Cables connect to rear contact terminals; cable entry is provided by outer explosion-proof enclosure.
• Connection-Cable Gland: No cable gland supplied. Glands are mounted on the explosion-proof enclosure.

3.Product Classification & Origin

HS Code: 8536500000
Country of Origin: China

4.Applicable Industries

• Suitable for: Chemical, grain-oil processing, shipbuilding, mining supporting and automation complete-set equipment industries. As built-in components inside explosion-proof control and operation boxes, they realize equipment start-stop, emergency-stop, gear switching and status indication.
• Practicality: YX0501 series covers push-buttons, emergency-stop buttons, illuminated push-buttons, key-operated buttons and rotary switches. Plastic and metal housings are available with various colors. Multiple contact configurations including NO, NC and NO+NC are supported, up to 6 contact sets can be assembled. They can be matched with indicator-light modules to satisfy diverse control logics.
• Safety Performance: Emergency-stop and key-lock structures prevent accidental operation. Metal housing provides better impact resistance. Components shall not be used bare. They shall be fitted inside explosion-proof enclosures to guarantee stable and reliable control-circuit performance.
