The most commonly used thread design for photoelectric laser reflective sensors in automation technology is the M18 style. A sturdy metal casing can reliably detect objects in harsh industrial environments. The characteristics of these devices are long-distance, long-term stability, and high switching frequency. The diffuse reflectance sensor ensures very accurate background suppression, thereby preventing accidental switching even in demanding applications.
The product line includes beam passing sensors, retro reflective sensors, and diffuse reflective sensors, each with or without installation options. In demanding applications, precise adjustment of the application is achieved through potentiometers or buttons. The photoelectric sensor has teaching, distance measurement, lighting, and dimming modes. For diffuse reflection sensors, the background suppression mode can be easily set through buttons.
A wide range of system components ensures easy and secure integration into applications.
Working principle of M18 laser reflective sensor
A regression reflection laser sensor is a sensor that uses the principle of reflection to achieve photoelectric control, mainly used to detect the presence and position of target objects. This type of sensor is usually used in combination with a probe and a reflective plate. The light emitted by the transmitter is reflected back by the reflective plate, and the receiver can detect the presence of the target object after receiving the light signal

application of M18 laser sensor in industrial automation
Limiting and positioning: In mechanical automation production lines, M18 laser sensors can be used to detect the position of workpieces, ensuring that they move and position according to predetermined paths.
Detection and counting: Sensors can detect the passage of objects, thereby counting or triggering subsequent actions such as packaging, sorting, etc.
Speed measurement: By measuring the time it takes for an object to pass through a sensor, the speed of the object can be calculated.
