Pepperl + Fuchs RL28-8-H-700-RT/47/105 | Diffuse Photoelectric Sensor | 700 mm | Red-Light | PNP NO | IP67
Overview
The RL28-8-H-700-RT/47/105 is a compact red-light diffuse photoelectric sensor engineered for precise object detection up to 700 mm. Featuring adjustable sensitivity, a bright alignment spot, and a rugged IP67 housing, it delivers consistent performance on dark, shiny, or multicolored targets in demanding industrial environments.
Key Features
-
700 mm diffuse sensing distance with background suppression
-
Visible red-light LED for quick alignment
-
PNP, normally-open (NO) switch output
-
10 – 30 V DC operating voltage
-
High switching frequency (~1 kHz) for fast processes
-
Potentiometer for sensitivity and range adjustment
-
Dual LEDs: power ON (green) and output status (yellow)
-
Reverse-polarity and short-circuit protection built in
-
Slim plastic housing with M8 side-mounting holes
-
IP67 ingress protection for water- and dust-tight sealing

General-purpose detection where space is limited and IP67 is required
Why Choose the RL28-8-H-700-RT/47/105
-
Extended 700 mm range covers most mid-distance detection tasks.
-
Bright red spot simplifies alignment, cutting commissioning time.
-
Fast 1 kHz response keeps pace with high-speed automation.
-
Robust IP67 housing resists dust, splash, and cleaning cycles.
-
Built-in protections ensure long service life and reduce downtime.
