Photoelectric Sensors
Photoelectric sensors use light and optics to detect object presence or distance. They provide an output based on object detection or distance criteria. Photoelectric sensors from brands such as Autonics, Contrinex, Datalogic, di-soric, Eaton, Leuze, Micro Detectors, and Wenglor, as well as our own AchieVe, AutomationDirect, and ProSense brands, can detect a wide variety of materials and measure distances from a few millimeters up to hundreds of meters.

Photoelectric Sensors Overview
Background Suppression
Newest Additions!
- AchieVe FKL series 18mm tubular metal photoelectric sensors
- Autonics miniature photoelectric sensors
- AchieVe FDM series 12mm tubular photoelectric sensors
Diffuse photoelectric sensors with background suppression detect objects by sensing emitted light reflected directly from the target. They offer reliable detection while filtering out reflections from surrounding objects. Blue light models accurately sense dark, shiny, or highly reflective targets.
Diffuse
Newest Additions!
- AchieVe FKL series 18mm tubular metal photoelectric sensors
- Autonics miniature rectangular photoelectric sensors
- Wenglor OPT25 series laser distance measurement photoelectric sensors
- AchieVe FDM series 12mm tubular photoelectric sensors
Diffuse photoelectric sensors consist of an emitter and receiver combined into a single compact housing. They sense presence, color, or contrast by emitting a light beam and sensing the light reflected directly from the target. They are easy to install and adjust but have short sensing distances.
Retroreflective
Newest Additions!
- AchieVe FKL series 18mm tubular metal photoelectric sensors
- Autonics miniature rectangular photoelectric sensors
- AchieVe FDM series 12mm tubular photoelectric sensors
Retroreflective sensors bounce light off a fixed reflector and determine a target's presence when it breaks the beam. They have longer sensing distances than diffuse sensors but require alignment. Polarized retroreflective sensors improve detection accuracy by filtering out ambient light sources.
Through-Beam
Newest Additions!
- AchieVe FKL series 18mm tubular metal photoelectric sensors
- Autonics miniature rectangular photoelectric sensors
- AchieVe FDM series 12mm tubular photoelectric sensors
Through-beam photoelectric sensors consist of an emitter and a receiver in separate housings. The emitter sends a beam of light to the receiver, which determines a target is present when the beam is interrupted. These sensors offer the longest sensing distances but require precise alignment.
Fiber Optic Sensors
Fiber optic sensors provide a remotely mounted electronics and optics package with fiber optic extensions to the sensing area. They offer supreme noise protection, and their small size is perfect for extremely tight locations or where even low-power electronics are not allowed.
Fork Sensors
Fork sensors (also called slot or "U" sensors) offer advantages over standard through-beam sensors, including identical mechanical / optical axis, operational reliability and repeatability with transmitter and receiver built into the same housing.
Reflectors, Lens Adapters and Splitters
Newest Additions!
- Wenglor signal splitter
Reflectors, lens adapters, shutters, and splitters are available for proper operation and detection or to alter the size and/or path of the emitted light for specialized installations.
Mounting Brackets and Rods
Brackets and adapters are available in various materials for mounting tubular and rectangular photoelectric sensors.
Sensor Tester and Spare Parts
Replacement hex nuts and a sensor tester are available to securely install and validate the operation of photoelectric sensors.
