Details :

  • Soldered/welded connection
  • Micro switch
  • Low pressure loss
  • Compact design
  • Threaded connection
  • Plug DIN 43650-A / ISO 4400


Characteristics : The devices function via the principle of a spring-supported paddle, and the magnetic triggering of a micro switch.

Handling and operation :

  • Include straight calming section of 5 x DN in inlet and outlet
  • When tightening the union nut, the connection piece must be countered using an open-ended spanner (SW 19).
  • If the media are dirty, install a filter (use magnetic filter for ferritic components).
  • It must be ensured that the values given for voltage, current, and power are not exceeded.
  • When switched on, a load must be connected in series.
  • The electrical details apply to ohmic loads. Capacitive and inductive loads must be operated using a protective circuit.


Options :

  • Connection for round plug-in connector
  • Signal lamp red or red/green in the plug DIN 43650-A
  • Gold contact 125 V AC / 30 V DC, 100 mA
  • Protective bellows
  • Switching ranges for oil or gas
  • Special values
  • Adhesive PVC fitting


Ordering information :

  • Specify direction of flow, medium, and switching range.
  • For oils, state viscosity, temperature and designation (e.g. ISO VG 68) (enquire about range).
  • For gases, state pressure (relative or absolute), temperature and medium (e.g. air) (enquire about range).
