UM3K Flow Switch

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).
