Photoelectric Sensors
Photoelectric sensors utilise light intensity-based detection principles to detect target presence/absence. There are several different types of photoelectric sensors, including reflective, retro-reflective, and thru-beam models. Photoelectric sensors offer a variety of benefits, including durability, application versatility, ease-of-use, and low cost.
Products Lineup : Photoelectric Sensors
The LR-X Series is a remarkably small laser sensor capable of detecting targets based on position and is unaffected by colour, surface finish, or shape. Impressive durability is achieved with its food-grade stainles steel housing (SUS316L), high IP ratings, and guarded cable. Position changes as small as 0.5 mm are possible, along with automatic and real-time intensity adjustment to ensure stable detection on any target.
The LR-T Series of reflective sensors represents a seamless fusion of innovative technology and robust functionality.
Laser sensor capable of detecting targets based on both position and contrast (detectable distance: up to 500mm).
High-power, dual LED-type photoelectric sensors for improved performance and ease of use.
Automatic calibration type. Virtually eliminates all detection and stability problems inherent with conventional photoelectric sensors.
High environmental resistance & cable extension capabilities provide increased installation versatility
The new PX Series heavy-duty industrial photoelectric sensors. Rugged industrial sensors designed for use in harsh environments.
Products Lineup : Colour Sensors
This Full-Spectrum sensor features unmatched detecting capabilities that allows it to complete the simplest to the most complex applications with ease.
Simple one-touch calibration with a dual digital display and ability to store up to 8 colours. Colour, lustre and fluorescent/UV sensing heads all connect to CZ-V20 Series amplifier.
A beam of light is emitted from the light emitting element and is received by the light receiving element.
Type 1 - Reflective Models
Both the light emitting and light receiving elements are contained in a single housing. The sensor receives the light reflected from the target.
Detection occurs when the light beam, emitted to the target, is reflected by the target and received.
Space-saving (requires installation of sensor unit only)
Adjustment of optical axis not required
Reflective transparent objects detectable
Colour differentiation possible
Type 2 - Thrubeam Models
The transmitter and receiver are separated. When the target is between the transmitter and receiver, the light is interrupted.
Detection occurs when the target crosses the optical axis between the photoelectric sensor's transmitter and receiver.
Long-detecting distance
Stable detecting position
Opaque objects detectable regardless of shape, colour or material
Powerful beam
Type 3 - Retroreflective Models
Both the light emitting and light receiving elements are contained in same housing. The light from the emitting element hits the reflector and returns to the light receiving element. When a target is present, the light is interrupted.
Detection occurs when the target crosses the optical axis between sensor head and reflector.
Reflector allows installation in a limited space
Simple wiring
Longer detecting distance than the diffuse-reflective sensor type
Easily-adjustable optical axis
Opaque objects detectable regardless of shape, colour, or material
Frequently Asked Questions About Photoelectric Sensors
A photoelectric sensor emits a light beam (visible or infrared) from its light-emitting element. A reflective-type photoelectric sensor is used to detect the light beam reflected from the target. A thrubeam type sensor is used to measure the change in light quantity caused by the target crossing the optical axis.
