Photoelectric sensors can sense distances up to 200 m, operate with ac, dc, or ac/dc (universal voltage) and offer E/M relay outputs.
Fibre Optic Sensor
Fiber optic sensors are ideal for harsh conditions: high vibration,extreme heat, and wet, explosive, or corrosive environments. In confined areas, the flexible fibers can be positioned precisely
Because ultrasonic sensors use sound waves rather than light, they are ideal for sensing uneven surfaces, liquids, clear objects, and objects in dirty environments.
Laser diode sensors combine the alignment advantages of a visible sensing beam with the increased sensing range of a laser. They operate on dc or ac/dc (universal voltage).
Class 1 and Class 2 devices are available.
Slot sensors detect objects that pass
Between the two arms—one with the emitter, the other with the receiver. The fixed slot width provides reliable opposed-mode sensing of objects as small as 0.30 mm.
Radar sensors use Frequency Modulated Continuous Wave (FMCW) radar to reliably detect moving or stationary targets, including cars, trains, trucks and cargo in extreme weather conditions
Color Mark Sensors
Color sensors detect subtle color contrasts to inspect registration marks, using one, two or three color LEDs.
True Color Sensors
True color sensors accurately analyze and compare color to color or varying intensities of one color.
