Signal description:
NPN output: NPN output is one of the three-wire switching volume output. When the sensor is induction, the output is a low level signal, and the output of the sensor is a high resistance, and the high and low level can be determined by external access pull resistance. The NPN output can directly control the current within 300mA.

High and low level signal output: the sensor provides a high and low level signal, which is suitable for small current control of large current, control of external circuit, MCU signal identification and judgment, etc.
Switching volume output: the signal sent by the switching volume sensor is the contact signal, there are disconnected and closed two states, such as the sensor switch is a common switching volume sensor. The sensor switch is disconnected (or closed) when the object enters the sensor induction area and the switch closes (or disconnected) when the object leaves the sensor setting induction area.
UART serial output: Laser switch (except XKC-KL 800-V) with UART configuration function. Users can configure relevant parameters through the UART communication protocol, or specify the factory default configuration value. The default configuration value of PRO RANGE is shown in the following table.

Induction distance adjustment

1. Place approximately 60cm * 60cm kraft cardboard in the range of 100 c m(0.2m ~8m in front of the sensor according to user requirements).
2. The sensor is power-supply switched on.
3. Find the sensor button, and then hold down the button.
4. About 2-3 seconds after the indicator light is on, release the button and start entering the automatic adjustment sensing distance mode. The sensor and cardboard remain motionless, with no other objects in the middle. After waiting for about 2 seconds, the indicator light stops flashing to automatically save the data; automatically return to normal operation mode. The adjustment distance is completed.

Ranging characteristics

• The KL 800 is 0-20cm, and the data in this range is not credible.
• Ability to detect black (10% reflectivity) targets, with a measurement range of 0.2-2.5m.
• Ability to detect white (90% reflectivity) targets with a measurement range of 0.2-8m.
• The data is stable and reliable only when the measured target side length is greater than or equal to, the effective range side length. “Effective distance measuring side length”
• Deided by the field of view (the field of view generally refers to the receiving Angle and the emission Angle), the calculation formula is: d = 2 ∗ D · tanβ
• Where d represents the effective ranging side length, D represents the detection distance, and β is the receiving half angle 1° of KL 800, the general effective ranging

The corresponding relationship between side length and detection distance is shown in the table below:

detection range	1m	2m	3m	4m	5m	6m	7m	8m
Effective side long	3.5cm	7cm	10.5cm	14cm	17.5cm	21cm	24.5cm	28cm

Notes for use

1. The receiving device is disturbed by strong light (ordinary indoor light is not affected, when the light is too strong, the sensitivity is reduced and the distance becomes close). When installation, try to avoid direct light on the probe to make the induction distance close and affect the function.
2. During the installation, avoid working in the environment with high dust concentration (because the high concentration of dust is equivalent to inductive objects, which will make the sensor work by mistake) to avoid misoperation.
