The LITTLE-EX series of cable end float switches by Cynergy3 utilises a self-cleaning switching element to enable switching insensitive to humidity or condensation and hence use in widely fluctuating temperatures. These float switches are ATEX Ex II 1 G Ex ia IIC T6 certified and designed for use in hazardous areas. The switch is housed within a high density polyethylene floating body (please refer to the Chemical compatibility chart in Technical library) with centre of gravity carefully positioned near the cable entry. The LITTLE-EX series is supplied with 5m, 10m or 20m length of cable and can be operated in temperatures between -20°C and +40°C.

  • ATEX certified cable end float switch
  • Supplied with 5m, 10m or 20m cable
  • Self-cleaning design prevents buildup of solids
  • Switching element not affected by rapid temperature changes, humidity or condensation
  • Temperature range of -20°C to 40°C
  • It is necessary to use an Exia barrier with these switches
  • Contact form: C/O


Typical applications for the Cynergy3 LITTLE-EX float switches include:

  • Water tanks
  • Industrial waste water
  • Sewage
