Detection based on “light”
Method to choose Photoelectric Sensors as to environment

Other variations

There are various types of photoelectric sensors depending on environment or installation location. The following are typical classifications which allow you to select photoelectric sensors more suitable for your environment.

Classification based on whether the amplifier is separated or not

Self-contained type

Self-contained type

Setup and feedback is found on the sensor unit itself. These units are typically a little larger.

Separate-amplifier type

Separate-amplifier type

An amplifier is separate from the sensor head to allow for remote setting and feedback. This allows the sensor head to be smaller and more flexible to mount.

Classification based on housing material

Plastic housing type

Plastic housing type

The housing is made of plastic.
Most models are relatively lightweight; however, their frame strength is inferior to that of the metal housing type.

Metal housing type

Metal housing type

The housing is made of metal such as stainless steel. This type is robust and has long service life compared to the plastic housing type.
