IFM Photoelectric Sensors – Reflective & Distance Sensor
The IFM Photoelectric Sensor, manufactured by IFM, uses established operating principles such as through-beam transmission, retro-reflective return paths, and diffuse reflection to detect object presence, part positioning, and material contrast. These sensors incorporate optical emitters, receivers, signal processing circuits, and standardized mechanical housings in cylindrical or rectangular formats, with electrical interfaces including PNP, NPN, or relay outputs for industrial controllers.
One reference to IFM anchors the entity within its broader sensing portfolio for semantic continuity. Classification variants include the IFM through beam sensor, reflective detection, background suppression designs, and object verification types, depending on required application characteristics. An IFM photoelectric sensor or IFM photo sensor is defined by optical detection technology, emitter–receiver structural configuration, classified sensing modes, and standardized industrial interface types.

Frequently Asked Questions
What are the techniques of photoelectric sensor?
Photoelectric sensors primarily use three sensing methods: Through beam, Retro-reflective, and Diffuse or Reflective. Each method has distinct characteristics for target detection. The Through beam method involves separate transmitter and receiver units. Retro-reflective sensors use reflectors to return light to the receiver. The Diffuse method relies on light reflection directly from the target.
What is PNP and NPN sensor?
PNP and NPN sensors are types of three-wire sensors used in various applications. Both are powered by positive and negative leads. PNP sensors send a positive output to industrial controls when activated. Conversely, NPN sensors emit a negative signal in their “on” state. These differences stem from their internal circuit designs.
What is the output of a photoelectric sensor?
The output of a photoelectric sensor is typically digital or analog. Digital outputs switch on or off, often using a three-wire configuration. These configurations include PNP (sourcing output) or NPN (sinking outputs). This design allows for straightforward integration with various control systems.
