Zone 1 Hazardous Area Rated Incremental Encoders

The new EN42 hollow-shaft and EN44 hub-shaft incremental encoders eliminate the cost, guess work and hassle of installing a barrier thanks to encapsulated electronics. The EN series offers ATEX, CSA and IECEx triple certification and a powerful signal driver for universal use in oil & gas equipment applications.

ATEX, CSA, IECEx Triple Certified

With enforcement of regional certifications on the rise, the EN series is a flexible solution for zone 1 use with ATEX, CSA and IECEx certifications. The EN series also offers the industry’s leading operating temperature range of -50° to 100° C.

High Power Line Driver Available

The EN series offers a high power mosfet line driver (10-30 VDC) is for applications requiring a long cable run to ensure reliable signal output without sacrificing performance.

Easy to Install with No I.S. Barrier Needed

Both the EN42 and EN44 offer encapsulated electronics with increased safety interface for zone 1 use eliminating the need for a separate I.S. barrier and the guesswork to install one. The EN44 also offers a standard B100 mounting flange and integrated double helix coupling for easy installation.
