FS-CYL-B Series overview
This highly versatile FS-CYL-B Series (1/2"” NPT Conduit Entry) proximity switch is suitable for a wide variety of applications requiring a reliable signal.
By utilising proven magnetic technology, they can detect ferrous materials, such as carbon steel or stainless steel (17/4 or 400 series) at up to 2.3mm (0.09""). They come with volt-free SPCO/SPDT (Form C) contacts as standard.
In both hardwired and wireable models, the 2-bolt flange allows direct mounting to hydraulic or pneumatic cylinders.
Hazardous area certifications for the FS-CYL-B Series are listed below.
| 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 |
With Systematic Capability (SC3) as an element/subsystem, the FS-CYL-B series proximity switches meet the requirements of IEC 61508:2010 Routes 1H & 1S. In addition, they are suitable for safety-related systems ranging from SIL 2 with HFT=0 (1oo1) to SIL 3 with HFT =1 (1oo2).
