Banner Engineering introduces M18-4 self-contained photoelectric sensors. Featuring IP69K-rated 316 stainless steel housing, the heavy-duty 18 mm metal barrel sensor is suited for harsh industrial environments where abrasive chemicals and ingress fluid are present. Built with Advanced ASIC (Application Specific Integrated Circuit) technology, the dc-operated M18-4 sensors are also resistant to fluorescent light and offer crosstalk avoidance.
Featuring a bright visible red emitter beam, the M18-4 enables easy alignment and set-up. The M18-4 sensor offers a highly visible output and dual-function power and stability indicators. The indicators are comprised of one green and two yellow LED lights. Solid green indicates power is applied and the sensor is ready, while green flashing specifies a marginal sensing signal. The two bright yellow LEDs, visible from both sides of the sensor, indicate the output is conducting.
The M18-4 is available in opposed, polarized and non-polarized retroreflective, diffuse and fixed-field sensing modes. Diffuse models offer a 250 degree sensitivity potentiometer. The sensors operate in temperatures of -40 to +70 degrees celsius.
