FOSAI PRODUCT CATEGORY
Explosion-protected Encoders
Absolute encoder options for specified hazardous-area projects with project-level certificate and interface confirmation.
CATEGORY OVERVIEW
An explosion-protected encoder must be selected against the actual hazardous-area classification, protection concept, gas or dust group, temperature class and certified ambient range. A product name or enclosure appearance is not evidence of suitability. The exact certificate, model suffix, wiring method and installation must be reviewed per project.
SELECTION CHECKLIST
Compare the requirement before the model.
Temperature
Confirm temperature class and certified ambient range.
Certificate
Review the exact certificate and model suffix rather than a family statement.
Integration
Confirm interface, cable entry, grounding and installation requirements.

Before choosing this category
Can a standard encoder be installed inside an enclosure?
Hazardous-area compliance is a system and certification question; do not assume an enclosure alone makes a standard device suitable.
Is one Ex marking valid worldwide?
Acceptance depends on the certification scheme and local project requirements.
TECHNICAL SELECTION
Confirm the complete configuration.
Include measurement, interface, supply, mechanics, environment, documentation and quantity.
