FS-C Proximity Switch Certified for ATEX/IECEx/UKEx Ex db/tb IIC / IIIC T6 (Gas) T85°C (Dust) Rated for use in Gas & Dust Zone 1, 2, 21 and 22
For demanding and hazardous environments in which reliable signal detection is critical, the FS-C Series Proximity Switch with M18x1.0 Thread is specifically engineered with Ex d protection for Zones 1/21 or 2/22.
With their proven magnetic sensing technology, these switches detect ferrous materials like carbon steel or stainless steel (17/4 or 400 series) at distances up to 2.5mm (0.1"), making them ideal for harsh environments.
With its volt-free SPCO / SPDT (Form C) contacts, the FS-C Series can be configured as normally open or normally closed, providing operational flexibility in safety-critical environments. The switches' adaptability makes them well-suited to hazardous areas where precision and dependability are essential.
Euroswitch products are also available with multi-approvals including combinations of the following global and regional certification standards. The following hazardous area certifications apply to the FS- C Series.
| Explosion Proof: | IECEx & ATEX Ex d db tb (Zone 1 & 2 and Zone 21 & 22) UL/CSA Class I, Class II and Class III, Division 1 & Division 2 (Cl1 Div1 ; Cl2 Div1 ; Cl1 Div 2 ; Cl2 Div2) |
| Intrinsically Safe: | IECEx & ATEX Ex ia (Zone 0 & Zone 20) ¦ UL/CSA IS (Zone 0) |
| Other Regional Approvals Include: | EAC TRCU, INMETRO, KCs (KOSHA), PESO CCOE , ECAS ex, NEPSI CQST |
With an innovative integrated junction box/connection head, the FS-C Series offers multiple configuration options: hardwired or wireable (W, WL, WLR). In confined or hazardous spaces, this design eliminates the need for additional components, simplifying installation.
Engineered to meet the strict requirements of IEC 61508:2010 (Routes 1H & 1S) with Systematic Capability (SC3), the FS-C Series proximity switches are certified for use in safety-related systems. They support safety functions up to SIL 2 with HFT=0 (1oo1) and SIL 3 with HFT=1 (1oo2), ensuring reliability and compliance in critical applications within hazardous zones.
