A robust and versatile solution, the FS-D Proximity Switch (5/8″ UNF Thread) is designed for Ex db IIC T6 Gb and Ex tb IIIC T85°C Db applications requiring dependable signal detection.

Engineered with proven magnetic technology, it reliably senses ferrous materials, such as carbon steel or stainless steel (17/4 or 400 series), with a detection range of up to 2.5mm (0.1″). It is designed with volt-free SPCO/SPDT (Form C) contacts as standard, which makes it compatible with a wide range of applications.

Due to its compliance with IECEx and UL certifications, the FS-D Series is ideal for hazardous environments with strict safety standards. Additionally, it features a unique integrated junction box/connection head design, available in multiple wireable options (W, WL, WLR). This eliminates the need for additional components, enhancing functionality and reliability in space-constrained environments.

The FS-D Series is covered by the following hazardous area certifications.

The series meets the rigorous requirements of IEC 61508:2010 Routes 1H & 1S, achieving Systematic Capability (SC3) as an element/subsystem. It is suitable for safety-related systems performing functions up to SIL 2 with HFT=0 (1oo1) and SIL 3 with HFT=1 (1oo2). With advanced certification, cutting-edge design, and robust performance, the FS-D Series is an ideal choice for industrial and safety applications.

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. 

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.
