Benefits Introduce In Detail

Locating Non-Metallic Objects with Capacitive Proximity Switches

Capacitive proximity switches use non-contact sensing and solid-state circuitry to ensure long life and durability in the harshest corrosive environments. Compared to inductive proximity switches that detect metal objects, capacitive switches can detect almost any material and are widely used in the wood, paper, glass, plastic, and chemical industries.

Potentiometer Adjustment

These proximity switches are equipped with a potentiometer to adjust sensitivity. This function enables the switch to be precisely adjusted for specific applications.

Superior Noise Immunity

Switching power supplies, variable frequency motor drives, and high-power communication equipment are common in most factories. This equipment can generate high-decibel noise that interferes with the operation of proximity switches. For this reason, ifm capacitive proximity switches use a patented “charge balance” circuit design, which provides reliable noise immunity for efficient operation in high-noise environments.
