DISTANCE OF DETECTION: 5mm ± 10%. This is a normally close proximity sensor with a sensing distance of 5mm. WIDE APPLICATION: The proximity switch is a component widely used in the automatic control industry to detect, control and switch without contact.STANDARD OBJECT: Magnetic metal (detection distance decreases for non-magnetic metals). When the proximity sensor is close to a target object, it will send out a control signal. DELAY DISTANCE: <10% Detection distance. Non-contact detection avoids the sensor and the target object being damaged.STABLE PERFORMANCE: High sensitivity, fast response, stable performance. Note: The data are all manual measurement, please allow 1-3cm error, due to the light and display difference, there are will have some color difference, depending on the physical item received.
