FS-I Series Proximity Switches (M18 Thread) are designed for CI I, Div 1 Grps A-D & CI II, Div 1 Grps E-G CI,III applications that require a dependable signal. The magnetic technology in these switches enables them to detect ferrous materials like carbon steel and stainless steel (17/4 or 400 series) with precision over distances of up to 2.5mm (0.1″).
To enhance durability and reliability, the FS-I Series is available with hermetically sealed contacts, ensuring protection against environmental contaminants such as moisture, dust, and gases. As standard, these switches are equipped with volt-free SPCO/SPDT (Form C) contacts, making them suitable for demanding environments.
The FS-H Series is covered by the following hazardous area certifications.
| Explosion Proof: | IECEx & ATEX Ex d/db/tb (Zone 1 & Zone 21) ¦ UL/CSA IS (Class I, Div1) |
| Intrinsically Safe: | IECEx & ATEX Ex ia (Zone 0 & Zone 20) ¦ UL/CSA (Zone 0) |
| Other Regional Approvals Include: | EAC/TRCU, INMETRO, KCs, CCOE/PESO, ECAS ex, NEPSI/CQST |
Compliant with IEC 61508:2010 standards (Routes 1H & 1S) and equipped with a Systematic Capability (SC3), the FS-I Series is suitable for safety-related applications. For high-integrity applications, it supports safety functions up to SIL 2 with HFT=0 (1oo1) configurations and up to SIL 3 with HFT=1 (1oo2).
