Key Features
Compact 8‑Beam Detection Area
The DPR-0820-NPN-NC uses 8 infrared optical beams arranged with a 20 mm optical axis pitch. This configuration creates a compact 140 mm protection height for applications requiring multi‑beam detection in a relatively small vertical area.
140 mm Protection Height
With a 20 mm optical axis pitch and 8 optical beams, the DPR-0820-NPN-NC provides a 140 mm protection height. This makes it suitable for small machine openings, access areas and detection zones where approximately 140 mm of vertical coverage is required.
Fast Response <5 ms
The specified response time of the DPR-0820-NPN-NC is less than 5 ms, supporting industrial automation systems that require rapid detection of beam interruption.
NPN NC Output Configuration
The DPR-0820-NPN-NC uses NPN output with NC signal logic. Under normal beam transmission, the output is in the specified 0V condition. When a beam is interrupted, the output is removed (no output). This configuration allows the sensor to interface with industrial control systems requiring Normally Closed signal logic.
IP65 Industrial Protection
The DPR-0820-NPN-NC has an IP65 protection rating and is designed for industrial automation environments where dust and water exposure may occur.
SIL 2 Functional Safety Certification
The DPR Series is supported by SIL 2 Functional Safety Certification according to IEC 61508 through third‑party testing and certification.
How Does the DPR-0820-NPN-NC Work?
The DPR-0820-NPN-NC uses a through‑beam infrared detection method with a separate emitter and receiver. The emitter continuously sends multiple infrared beams toward the receiver to create a detection area.
Using Infrared LED Through Beam Detection technology, the DPR-0820-NPN-NC creates a protective detection field between the emitter and receiver. When an object enters or interrupts the detection area, the sensor detects the beam interruption and provides an output signal to the industrial control system.
Detection Process
- Infrared Beam Transmission — The emitter generates multiple infrared beams and sends them toward the receiver.
- Detection Area Creation — Eight optical beams are arranged at a 20 mm optical axis pitch, creating a 140 mm protection height.
- Object Detection — When an object enters the detection area, one or more infrared beams are interrupted.
- Signal Output — The receiver processes the interruption and changes the output according to the DPR-0820-NPN-NC NPN NC configuration.
