The FS-M Series Proximity Switch (M18 Thread) is specifically designed for IECEx & ATEX Globally Certified, US, Brazil, UAE, Russia, India, China, Korea and Taiwan markets for hazardous environments where safety and accuracy are critical.

These switches utilise advanced magnetic technology to detect ferrous materials such as carbon steel or stainless steel (17/4 or 400 series) at distances up to 2.5mm (0.100″), ensuring reliable operation even in extreme conditions. The inclusion of volt-free SPCO/SPDT (Form C) contacts as standard enhances versatility and safety.

In hazardous environments where space is a concern, the FS-M Series offers a side-exiting lead option to minimise overall switch length, making it ideal for compact installations.

FS-M Серия покрывается следующими сертификатами по опасным зонам.

Доказательство взрыва:	IECEx & ATEX Exd (Зона 1 & Зона 21)
Искренне безопасно:	IECEx & ATEX Exia (Зона 0 и Зона 20) ¦ UL/CSA IS (Зона 0)
Другие региональные разрешения включены:	EAC/TRCU, INMETRO, KCs, CCOE/PESO, ECAS ex, NEPSI/CQST

FS-M proximity switches are engineered to comply with IEC 61508:2010 Routes 1H & 1S, achieving Systematic Capability (SC3) as an element/subsystem. These switches are suitable for integration into safety-related systems performing critical safety functions up to SIL 2 with HFT=0 (1oo1) and SIL 3 with HFT=1 (1oo2), ensuring robust performance and compliance in hazardous applications.

The FS-K Series Proximity Switch (M18 Thread) is designed to function in extreme conditions, with temperatures up to +400°F / 204°C, and compliant with stringent UL and CSA dust group classifications. Leveraging advanced magnetic sensing technology, these switches reliably detect ferrous materials such as carbon steel or stainless steel (17/4 or 400 series) at distances of up to 2.5mm (0.1″). Their volt-free SPCO/SPDT (Form C) contacts ensure reliable and versatile signal switching.

With an optional side-exiting lead configuration, the FS-K series provides optimised installation in space-constrained environments.

Hazardous area certifications for the FS-K Series are listed below.
