Our photoelectric sensors offer you a high-quality, low-cost alternative to other suppliers of industrial sensors.

Our photoelectric sensors offer you a high-quality, low-cost alternative to other suppliers of industrial sensors.

We offer a variety of industrial sensors in different shapes and sizes to be used in a wide range of short or long-distance sensing applications.

Photoelectric sensor offerings now include high performance rectangular models, and both LED photo sensors and laser photo sensors are available. Options include metal, stainless steel and plastic body models in various sizes.

QuestionWhy is switching frequency important?
AnswerSwitching frequency is the speed in which a sensor detects an object, resets, and senses another object. For example, if a sensor has a switching frequency of 100 Hz (100 cycles peer second) it can detect a maximum of 100 objects per second. This is very critical in many applications such as gear rotation measurement.

Diffuse Photo SensorsDiffuse Photo Sensors

Lowest-cost, with one-point installation. Less-accurate than through-beam or reflective, with longer setup time.
