Specifications:
The document details the design and specifications of proximity switches from the IGEXHa series, available in sizes M12x1, M18x1, and M30x1.5. These sensors are designed for flush and non-flush installations with operating distances ranging from 2 mm to 15 mm depending on the model.

Ex Area of Use:
These sensors are suitable for use in hazardous areas, specifically Gas Zones 0/1 and Dust Zones 20/21. They are certified under ATEX and IECEx standards with certificate numbers EPS 17 ATEX 1 173 X and IECEx EPS 17.0087X.

Ex Marking:
For gas, the marking is II 1G Ex ia IIC T6 Ga, and for dust, it is II 1D Ex ia IIIC T145°C Da.

Temperature Ratings:
The ambient temperature range for Gas Zone 0 is -20°C to +60°C, and for Gas Zone 1, it is -25°C to +75°C. The sensors can handle medium temperatures up to +140°C in Dust Zones 20 and 21.

Maximum Values:
The maximum electrical values are Ui = 12.6 V, Ii = 15.9 mA, Pi = 50 mW, Ci = 66.2 nF, and Li = 1.2 mH.

Materials and Protection:
The housing is made from AISI 316 Ti and PEEK, offering protection levels of IP 68 (3 bar) and IP 69, making them resistant to high-pressure cleaning.

Connection:
The sensors come with a 2 m FEP-cable (2x0.34 mm²) and can be connected to amplifiers like the IKMb 122 Ex series.

Additional Notes:
Proximity switches with cable lengths greater than 2 m are available upon request. These sensors are categorized under Gas-Ex Category 1 and Dust-Ex Category 1, ensuring intrinsic safety in Zone 0/20 environments.
