ATEX and IECEx certified: Incremental encoder with a solid shaft
The incremental encoder Ex FG 40 with a solid shaft design is an rugged and at the same time reliable device for measuring speed that has been constructed for use in hazardous areas in heavy industrial applications. As a further development of the proven FG-40 series it is designed to offer extremely high resistance to shock and vibration loads as well as ingress protection IP66 (salt water proof casing). Resolution as high as 62500 pulses per revolution ensures precise measurement results even in harsh conditions. The encoder is optionally equipped with 2 systems, as desired with HTL, TTL or sin/cos signal output respectively. The flameproof casing with detachable terminal box cover facilitates connecting the cable during on site installation. That in turn means it is possible to use different cable lengths to connect the same device type. The encoder is certified to EN 60079 (ATEX) and IEC 60079 (IECEx) for applications in Zones 1 and 2 (gas) as well as Zones 21 and 22 (dust).
