Baumer HeavyDuty Incremental Encoder
Product Family: POG 9 (ATEX)
Serial Number: 700002497080
1. General Description
The Baumer POG 9 is a HeavyDuty incremental encoder designed for extreme reliability in harsh industrial environments. This specific model is certified for use in hazardous areas (ATEX), making it suitable for applications in oil and gas, chemical plants, or any area with potentially explosive gas or dust.
It features a robust, solid shaft design with a EURO flange, optical sensing for high precision, and a powerful HTL (Push-Pull) output driver for excellent noise immunity and signal transmission over long distances.
Key Features 🎯
- Hazardous Area Certified: ATEX certified for Zone 2 (Gas) and Zone 22 (Dust).
- HeavyDuty Construction: Extremely robust aluminum housing and double-sided bearings for high shock and vibration resistance.
- High Protection: IP 66 rating ensures protection against powerful water jets and dust ingress.
- Solid Shaft Design: Features a standard solid shaft with a EURO flange (B10) for secure mounting.
- High-Voltage Output: HTL (Push-Pull) output provides a strong, noise-immune signal.
