Photoelectric Sensors
The LR-X Series is a remarkably small laser sensor capable of detecting targets based on position and is unaffected by color, 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 (0.02 inch) are possible, along with automatic and real-time intensity adjustment to ensure stable detection on any target.
The LR-Z Series is capable of detecting objects based on position or contrast, allowing it to reliably detect metal targets, dark targets, transparent targets, contrast changes, etc. The series is housed in a rugged metal body and offers a simple one button teach. It has a range of up to 500mm (19.69") and offers hard wired, M8 connector, and M12 connector cable options.
The LR-T Series detects objects based on position and offers extended range to allow for flexible mounting. It is housed in a rugged metal housing, has a simple one button teach and is unaffected by color, surface finish or angle. This series has a range of up to 5m (16.4') and offers hard wired and M12 connector cable options.
The PR-M/F Series is the smallest metal photoeye in its class with an SUS316L stainless housing and offers both thrubeam and reflective options. Each model features a fixed field, meaning no calibration is required. This series has a range of up to 1.2m (3.94') and offers hard wired and M8 connector cable options.
The PR-G Series is a heavy duty general purpose photoelectric sensor in a metal housing with high power and easy trimpot adjustment. It has a range of up to 30m (98.4') and offers hard wired, M8 connector, and M12 connector cable options.
The PZ-G Series is a general purpose photoelectric sensor in a resin housing with high power and easy trimpot adjustment. It has a range of up to 40m (131.2') and offers hard wired, M8 connector, and M12 connector cable options.
The PZ-V/M Series automatically increases power when dirty, is in a durable resin housing, has background suppression, and is unaffected by color or angle. It has a range of up to 10m (32.8') and offers hard wired, M8 connector, and M12 connector cable options.
The PX Series has high power and is highly robust. It features stainless steel sensing heads that are water and oil resistant along with an amplifier that provides dual outputs. It has a range of up to 40m (131.2') and offers hard wired and M12 connector cable options.
The PS-N Series offers a variety of sensor heads; including ultra-thin, compact, and chemical-resistant variations. It has a range of up to 6m (19.69') and offers hard wired and M8 connector cable options.
Color Sensors
The LR-W Series can detect any difference in appearance (including color) and is in a durable metal housing. It has one touch calibration and can store up to 16 colors with an optional controller. This series has a range of up to 500mm (19.69") and offers hard wired and M12 connector cable options.
Simple one-touch calibration with a dual digital display and ability to store up to 8 colors. Color, luster and fluorescent/UV sensing heads all connect to CZ-V20 Series amplifier.
Pattern Matching Sensor
The AI Series detects targets over an area when position is not fixed, reflection is unstable, or to differentiate products. By covering an area, targets that are misaligned or rotated can be easily detected. This series has a range of up to 160mm (6.30") and offers hard wired and M8 connector cable options.
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.
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
Color 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, color 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, color, or material
