The S18-2 compact photoelectric sensors from Banner Engineering (Minneapolis, MN) are now available in fixed-field background suppression mode configurations. The compact, self-contained sensors provide up to six detection ranges from 30 to 200 mm. Resistant to fluorescent light, the components also feature a small, bright red LED emitter beam.
S18-2 sensors include dual-function power and stability indicators: one green and two yellow LED lights. Solid green shows that 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.
Designed with a rugged ABS plastic housing, S18-2 sensors are sealed against water ingress. Operating temperature ranges from -40 to +70 °C.
