Explosion-proof Switches
ATEX & IECEx Certified Explosion-Proof Switches — 398 Schmersal Models
This category brings together the Schmersal EX range of ATEX and IECEx certified explosion-proof limit switches, position switches and safety interlocks for potentially explosive atmospheres — gas areas (Zones 1 and 2) and combustible-dust areas (Zones 21 and 22). Of the 398 models listed, 263 carry explicit ATEX certification data in their specifications, 17 are additionally IECEx certified, and 243 include SIL safety-integrity parameters for functional-safety circuits.
| Hazard type | Category (model suffix) | Typical zones | Example model | In stock |
|---|---|---|---|---|
| Gas + dust, low frequency | 3G/D | Zone 2 / Zone 22 | EX-AZM 170-11ZRK 24VAC/DC-3G/D | 117 models |
| Dust only | 3D | Zone 22 | EX-AZM 161SK-12/12K-024 -3D | 47 models |
| Gas + dust, likely occurrence | 2GD | Zone 1 / Zone 21 | EX-SHGV/B01/131+BO-2GD | 29 models |
How to narrow the choice: confirm the zone classification of your installation, then match the EPL/category (1G > 2G > 3G and 1D > 2D > 3D), the protection method (Ex d flameproof enclosure, Ex e increased safety, Ex ia intrinsic safety, Ex tb dust enclosure by housing), the gas group (IIA/IIB/IIC) and the temperature class (T1–T6) — plus the mechanical requirements: actuator type, contact configuration and cable entry. Not sure which layer applies to your plant? Our explosion-proof switch selection guide walks through each step, including how ATEX zones map to the NEC/UL Class I/II/III Divisions used in North America.
Every model is genuine Schmersal stock with worldwide shipping. Request a quote for datasheets, ATEX EC-type examination certificates or IECEx Certificates of Conformity, and current USD pricing.
