Fotek Square-type Inductive Proximity Sensor KL-05N 3-wire NPN NO

Fotek Proximity switch KL-05N Proximity sensor 10 to 30V DC, 5 mm Sensing distance, NPN NO, IP67, 2m Wire

The FOTEK KL-05N is a square-type, inductive proximity sensor used for non-contact object detection in industrial automation settings. It is a 3-wire NPN, normally-open (NO) model.

Key specifications

• Sensing distance: 5 mm.
• Voltage: 10 to 30 VDC.
• Output: NPN, normally-open (NO).
• Output load current: 150 mA.
• Response frequency: 800 Hz.
• Detection type: Inductive (for metal objects).
• Housing: Square, typically made of reinforced plastic.
• Protection rating: IP67, protecting it from dust and temporary submersion in water.
• Connections: Comes with a 2-meter long cable.

Working

As an inductive sensor, the KL-05N generates an electromagnetic field from its sensing face. When a metallic object enters this field, it causes a change in the sensor's inductance. This change triggers the sensor's output, switching its state to indicate the presence of the object.
