INTRATEXtm : intrinsically safe ATEX encoders
With the EU directive for explosive environments ATEX, BEI Ideacod successfully launched of its Explosion-Proof encoders. Now, its ATEX compliant range of encoders is completed with INTRATEXTM: intrinsically safe incremental encoders proposed within a whole intrinsic safety system.

After the successful introduction of its Ex-proof encoders, BEI IDEACOD launches INTRATEX™: intrinsically safe incremental encoders. Based on DIGISINE® technology, they are certified ATEX Ex II 1G/D, EEx ia IIC/B T4 for use in explosive atmospheres (gas and dust, zone 0 and 20). A complete intrinsic safety system with encoders, barriers (galvanically isolated or Zener) and cable assembly is proposed. With outer diameter of 58 mm, INTRATEX™ are available in shafted and hollow-shaft version.

Three standard electronics operating with existing barriers are available: one push-pull with supply 8 to 12V; one line driver RS422 with supply 4.5-6V for very high resolutions, one line driver RS422 with supply 4.5-8 V for standard resolutions. Protection against shorts-circuit is systematic,  protection against reverse polarity is available for the push-pull 8-12V. The resolution, which could be very high (max. 96000 cpt) can be programmed with special electronics. The frequency response could reach 1 MHz.
