FS-Q Series Overview
The FS-Q Series Proximity Switch with {{feature-key:mounting_product_description}} is designed for Hazardous area global standards compliance and high-pressure environments, offering exceptional versatility for applications demanding reliable signal performance.
By using advanced magnetic sensing technology, it can reliably detect ferrous materials, such as carbon steel and stainless steel (17/4 or 400 series), at distances upto 2.5mm. As standard, the switches are equipped with volt-free SPCO/SPDT (Form C) contacts.
FS-Q Series is certified for hazardous areas as follows.
| 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 |
Built to handle demanding conditions, the FS-Q Series meets the stringent requirements of IEC 61508:2010 Routes 1H & 1S, achieving Systematic Capability (SC3) as an element/subsystem. They are globally certified for use in safety-related systems performing key safety functions, with suitability up to SIL 2 with HFT=0 (1oo1) and SIL 3 with HFT=1 (1oo2), ensuring high-performing performance under pressure in high-stakes scenarios.
