Proximity Switch - Ferrous

UL & CSA Class I Division1 SPCO/SPDT Proximity Switches - FS-C Series
Certifications / Approvals




FS-C Series overview
The FS-C Series Proximity Switch (M18 Thread) is a versatile solution designed for CI I, Div 1, Grps A-D & CI II, Div 1 Grps E-G CI,III applications requiring dependable signaling. Using magnetic technology, it detects ferrous materials, including carbon steel and stainless steel (17/4 and 400 series), with a sensing range of 2.5 mm (0.1").
With its volt-free SPCO (Single Pole Change Over) or SPDT (Single Pole Double Throw) contacts, the switch can be used with numerous circuit designs.
This series is available in a hardwired configuration as well as with four innovative wired options (W, WL, WLR, WLRT). The design incorporates a junction box and connection head in one package, simplifying installation and reducing the need for additional components, especially in areas with limited space.
The FS-C 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, CCC-Ex |
FS-C Series proximity switches are designed to meet rigorous safety standards, conforming to IEC 61508:2010 Routes 1H & 1S, and achieving Systematic Capability (SC3) as an element or subsystem. As well as performing safety functions up to SIL 2 with HFT=0 (1oo1) and SIL 3 with HFT=1 (1oo2), they are suitable for integration into safety-related systems.
