Series Overview
The FS-E Series Proximity Switch (M18 Thread) is highly versatile and can be used in a multitude of applications where a reliable signal is required. Utilising proven magnetic technology enables them to sense ferrous material, such as carbon steel or stainless steel (17/4 or 400 series) at up to 2.5mm (0.1"). Volt free SPCO/SPDT (Form C) contacts as standard.
The FS-E Series is available either hardwired or with one of three wireable options (W, WL, WLR) which utilises our pioneering integrated junction box/connection head design. Euroswitch wireable proximity switches alleviate add on components and allow installation where space is at a premium.
The FS-E Series is covered by the following hazardous area certifications.
| Explosion Proof: | IECEx & ATEX Exd (Zone 1 & Zone 21) ¦ UL/CSA (Class I & II, Div1 & Div2) |
| Intrinsically Safe: | IECEx & ATEX Exia (Zone 0 & Zone 20) ¦ UL/CSA IS (Zone 0) |
| Other Regional Approvals Include: | EAC/TRCU, INMETRO, KCs, CCOE/PESO, ECAS ex, NEPSI/CQST |
The FS-E series proximity switches meet the requirements of IEC 61508:2010 Routes 1H & 1S with Systematic Capability (SC3) as an element/subsystem, and are suitable for use in safety related systems performing safety functions up to and including SIL 2 with HFT=0 (1oo1) and SIL 3 with HFT =1 (1oo2).
