Available in fixed-field background suppression mode configurations, S18-2 Photoelectric Sensors provide up to 6 detection ranges from 30–200 mm. Self-contained units are resistant to fluorescent light and offer high level of crosstalk avoidance. With bright red LED emitter beam, sensors are easy to align to target, and ensure very small shifts in detection range caused by target color variation. Sensors operate from -40 to +70°C and include dual-function power and stability indicators.
