FS-Series - FerroSwitch FS-L & M Series - SPDT The FS-L Series (Imperial 5/8" UNF Thread) & FS-M Series (Metric M18 Thread) proximity switches have the same great variety of options as the FS J & K series only with a longer 68.60mm / 2.70” thread allowing them to be more adjustable. 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. Mounting Thread: 5/8"-18 UNF or M18x1.0 Thread Length: 68.60mm / 2.70" Long FS-L Imperial Version 5/8-18 UNF Thread No conduit entry FS-M 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.
