FS-Series - FerroSwitch FS-J & K Series - SPDT The FS-J Series (Imperial 5/8" UNF Thread) & FS-K Series (Metric M18 Thread) proximity switches have the widest range of Zone 0 certifications and temperature options of any product of its type. It is also our most compact and cost effective solution in the FS Series range making it a popular choice. Features + Sensing range <2.5mm (0.100"). Can be extended with target magnet. + Repeatability approx. 0.05mm (0.002"). + Volt free SPDT/SPCO (Form C) 4A contacts as standard. + -60°C to +204°C / -76°F to +400°F temperature options. Options + Global Certification (Multi certified options available). + Metric or Imperial threads. + Optional side exit leads. FS-J Mounting Thread: 5/8"-18 UNF or M18x1.0 Thread Length: 47.60mm / 1.87" Long FS- 1 - Product Series 2 - Certification 3 - Material 4 - Temperature Range 5 - Additional Options 6 - Connection Options FS-J Imperial Version 5/8-18 UNF Thread No conduit entry FS-K Metric Version M18x1.0 Thread No conduit Entry Refer to diagram(s) above for dimensions of product variants. Sensing Ranges Magnet Range Given sensing ranges relate to primary sensing face. Secondary and Tertiary sensing faces will see a reduced sensing range.
