The Banner Engineering M18-4 self-contained photoelectric sensors feature a robust IP69K-rated 316 stainless steel housing. The heavy-duty 18 mm metal barrel sensor is suitable for harsh industrial environments where abrasive chemicals and ingress fluid are present. Built with advanced ASIC technology, the DC-operated M18-4 sensors are also resistant to fluorescent lighting and offer a high level of crosstalk avoidance.

Featuring a powerful and bright visible red emitter beam, the M18-4 allows for easy alignment and set-up. For added ease of use, the M18-4 sensor also offers a highly visible output, and dual-function power and stability indicators. The indicators comprise one green and two yellow LEDs. 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.

To accommodate diverse applications, the M18-4 is available in opposed, polarised and non-polarised retroreflective, diffuse and fixed-field sensing modes. For increased flexibility, diffuse models offer a robust 250° sensitivity potentiometer. A wide operating temperature range of -40 to +70°C ensures optimal performance for diverse applications.
