The most complete range of the ATEX encoders market has been developped by BEI IDEACOD: explosion proof and intrinsically safe encoders.
>> Pulsatex+
Delivering pulses, PULSATEX encoders are available with a 12mm solid shaft or a 30mm hollow through shaft.
Certified EEx d IIC T6, they have been developped for category 2 applications: zone 1 (gas) and 21 (dust).

>> Intratex
After the success of the marketing of its flame-proof encoders, BEI IDEACOD launches INTRATEX: range of incrémental encoders with intrinsic safety.
These encoders are especially designed for explosive atmosphere gas or dust. Their grounds of application are the chemical industry (painting, solvent, perfumes, rubber), the textile, the food one, wood, storage or petrochemistry....
They are labeled Ex II 1G/D, Eex ia IIC/b T4.
