Fuwei FKN10 series proximity switch is a non-contact sensor device that can detect transparent and opaque objects such as metal (e.g. iron, steel, copper), plastic, glass, wood, water, magnets, etc. Its working principle is mainly based on the change of capacitance value between the object and the receiving pole plate to detect the object's proximity or departure, and to convert the signal into switching state, which is widely used in the field of industrial automation.

Features and advantages

Non-contact detection: Capacitance proximity switches do not need to be in direct contact with the object to be measured, so wear and tear and pollution caused by contact can be avoided.

Wide applicability: capacitive proximity switches can detect metallic objects as well as non-metallic objects. For non-metallic objects, the action distance depends on the dielectric constant of the material; the higher the dielectric constant, the greater the action distance that can be obtained.

High sensitivity and fast response: Capacitive proximity switches are characterized by high sensitivity and fast response, which can quickly detect the approach or departure of objects.

Wide range of application scenarios

Capacitive proximity switches are widely used in industrial automation, robotics, mechanical

Multi-protection

Not only to protect the product itself, but also to protect the equipment from damage, safer during the work.

Short circuit protection

Protects not only yourself but also the load from being burned out in case of a short-circuit problem.

Overload protection

Automatically protects the load when it becomes unstable or when there is a problem that causes the current to increase.

Polarity protection

The product power cord positive and negative polarity reversal will not burn the product.
