Unique Engineering

The IFM PK6522 is a mechanical-electronic pressure switch designed for reliable switching and control in pressurized systems up to 100 bar (1450 psi). This compact device combines a mechanical adjustment interface with solid-state PNP switching outputs, making it an excellent fit for hydraulic, pneumatic, and general industrial automation applications.

It features an adjustable dual switching range via two setting rings on the housing—allowing precise control over both upper and lower thresholds without the need for software or tools. The device incorporates a robust metal thin-film stainless-steel sensing cell, offering high accuracy, excellent overload resistance, and long service life.

• Tool-free adjustment with visible setpoint indicators for easy calibration on-site

• High durability for demanding environments (IP67, shock/vibration resistant)

• Dual PNP outputs allow integration into control and alarm systems

• Compact and robust—ideal for mobile and industrial machinery

• No software required—fully hardware-configurable via control rings

• Hydraulic pressurization and overpressure protection

• Pneumatic system pressure monitoring

• Industrial machinery status indication and cutoff

• Process automation where fast switching and reliability are critical
