Banner debuts M18-4 photoelectric sensor

Jan. 25, 2016 – Banner Engineering has announced its M18-4 self-contained photoelectric sensors, which feature an 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, says the company. Built with Advanced ASIC (Application Specific Integrated Circuit) technology, the dc-operated M18-4 sensors promise to be resistant to fluorescent light and boast a high level of crosstalk avoidance. Featuring a red emitter beam, the M18-4 offers dual-function power and stability indicators, 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 yellow LEDs, visible from both sides of the sensor, indicate the output is conducting. To accommodate different applications, the M18-4 is available in opposed, polarized and non-polarized retroreflective, diffuse and fixed-field sensing modes.
