Product catalog summary

General Characteristics
The K-F series pressure switches are designed with either diaphragm or piston sensing elements, depending on the pressure range. The K4 series features NO or NC electrical contacts, while the F4 series includes SPDT contact arrangements. The set point is adjustable via a screw on the switch head, and mechanical holders protect the electrical contacts from pressure overload. Electrical connections are faston type, with optional rubber cup or DIN plug protection. These switches are suitable for oleodynamic and pneumatic applications, such as machine tools and pumps, serving as safety devices.

Specifications
- Pressure range: 0.05 to 400 bar
- Easy adjustment and installation

Adjustable Ranges
Various models offer different pressure ranges and maximum temperatures, with hysteresis and accuracy percentages provided. For example, the F3S model ranges from 0.05 to 0.5 bar with a maximum temperature of -20/+80°C.

Technical Data
The K4, F4, and F3S models have different body materials, process connections, and electrical contacts. Protection class is IP40, with options for stainless steel bodies and various diaphragm materials like Viton and PTFE.

Adjustment Procedure
To adjust the switch point, rotate the setting screw on the switch head. Clockwise rotation increases the set point, while anticlockwise rotation decreases it. The DIN 43650 plug allows adjustment without removing the plug.

Wiring and Dimensions
Wiring options include NO, NC, and SPDT configurations. Dimensions and specific wiring instructions are provided for each model.

Nomenclature
The nomenclature system includes type, adjustable range, sensing element, electrical contact, process connection, body and diaphragm material, electrical connection, and protection class.
