YX0503 Flameproof Potentiometer

Technical Data

1.Explosion-proof Type

• Standards Implemented:YX0503 potentiometer is an internal component for explosion-proof enclosures without separate Ex certificate and must be installed inside enclosures complying with GB3836 for explosive atmospheres.
• Applicable Hazardous Areas: This potentiometer cannot be used bare in explosive hazardous areas. It can be applied in relevant gas and dust hazardous zones only after being assembled within certified explosionproof enclosures.
• Ex Marking: Gas protection: The potentiometer itself has no independent Ex rating. The explosion-proof grade of complete set is determined by the matched explosion-proof enclosure.

2.Product Parameters

• Product Type: Panel-mount built-in potentiometer for explosion-proof enclosures, including single-turn and multi-turn types, for analog signal, speed and voltage adjustment.
• Certification: No separate Ex certification. It is internal component and shall be installed inside certified explosion-proof enclosure.
• Material: Main body made of polyamide, internal resistance element, plastic adjusting knob.
• Exposed Fasteners: No exposed fasteners. Thread locking structure for rear-of-panel mounting on 1-6 mm thick panel.
• Electrical-Rated Voltage: Max. 250V DC.
• Electrical-Rated Current: No rated current shown on datasheet. Rated power: single-turn 1W, multi-turn 2W, min. 0.1W.
• Protection-Ingress Protection: No independent IP rating for potentiometer. Protection class depends on complete explosion-proof enclosure.
• Protection-Ambient Temperature: Ambient temperature -40℃～+60℃; operating temperature -40℃～+75℃.
• Connection-Cable Cross-section: Terminals suitable for 2.5mm² cable.
• Connection-Cable Entry: No cable entry on potentiometer itself. Cables connect to rear terminals; cable entry is provided by outer explosion-proof enclosure.
• Connection-Cable Gland: No cable gland supplied. Glands are mounted on explosion-proof enclosure.

3.Product Classification & Origin
