Description
Product Overview
The uxcell RPR220 Photoelectric Switch is a high‑quality reflective optical coupling sensor designed for precise detection in a variety of electronic equipment. Packaged as a set of five 4‑pin modules, each sensor combines a gallium arsenide infrared LED transmitter with a silicon plane photoelectric triode receiver, delivering reliable ON‑OFF switching at a detection distance of 1‑13 mm. Built to meet an IP54 protection rating, the units resist dust and water splashes, making them suitable for both indoor and semi‑outdoor environments. Key specifications include a 30 V operating voltage, 30 mA current rating, normally open contact type, and a metal contact material that ensures durability and consistent performance over time. The compact dimensions of 22.8 × 4.9 × 6.3 mm allow easy integration into tight spaces, while the five‑position layout provides flexibility for multi‑channel applications.

Usage
These sensors are ideal for printers, scanners, copy machines, and any device that incorporates an inductive proximity sensor slot. Their fast response time and accurate detection make them perfect for controlling paper feed mechanisms, detecting object presence, and managing safety interlocks in automated systems. Because the RPR220 operates on infrared light, it can be used in low‑light conditions without interference from ambient lighting. Installers appreciate the straightforward wiring—four pins for power, ground, signal, and shield—allowing quick connection to standard control boards. The sensors also perform well in industrial automation, robotics, and conveyor systems where reliable object detection is critical for maintaining workflow efficiency.

FAQ
What is the maximum detection distance for the RPR220 sensor?
The sensor reliably detects objects within a range of 1 to 13 mm, making it suitable for close‑proximity applications such as paper feed detection and small object presence monitoring.
Can the sensor operate in dusty or humid environments?
Yes. With an IP54 protection rating, the RPR220 is designed to resist dust ingress and water splashes, allowing it to function effectively in workshops, factories, and semi‑outdoor settings.
Is the sensor compatible with standard 5 V control circuits?
While the sensor is rated for a 30 V operating voltage, it can be safely integrated into 5 V control circuits using appropriate voltage regulation or a resistor network to match the required signal levels.
How does the five‑position layout benefit my project?
The five‑position configuration enables you to monitor multiple zones or channels simultaneously, reducing wiring complexity and providing a streamlined solution for multi‑sensor installations.
What kind of support does uxcell provide after purchase?
uxcell offers technical assistance through email and phone, detailed installation documentation, and a warranty that covers any manufacturing defects, ensuring you have the resources needed for successful integration.
