What Is an Industrial Area Sensor?
An Area Sensor is a multi-beam photoelectric sensor that uses multiple light beams to create a detection area instead of relying on a single detection point.
Compared with a conventional single-point photoelectric sensor, an area sensor can detect objects passing through a defined detection zone, making it suitable for applications where object position, shape or movement direction may vary.
A typical industrial area sensor consists of:
- Emitter: Generates infrared beams.
- Receiver: Detects received infrared signals.
- Optical Beam Array: Creates a multi-beam detection field.
- Controller Interface: Provides output signals to industrial control systems.
The DAPPRA DPR Series uses a through-beam infrared detection structure with separate emitter and receiver units to provide stable object detection performance in industrial environments.
How Does the DPR-1640-NPN-NC Area Sensor Work?
The DPR-1640-NPN-NC operates using a through-beam infrared detection method.
The emitter sends multiple parallel infrared beams toward the receiver. When an object enters the detection area and interrupts one or more beams, the receiver detects the change and provides the corresponding output signal.
Detection Process
- The emitter generates infrared beams.
- Parallel beams travel across the detection area.
- The receiver monitors the beam status.
- Object interruption changes the output condition.
- The controller receives the NPN NC signal output.
The DPR-1640-NPN-NC uses parallel beam technology, which provides a defined detection area for industrial object detection applications.
How to Select the Right Area Sensor?
Selecting the correct area sensor requires matching the sensor specifications with the actual detection requirements of the application.
The main selection factors include:
- Object size requirement
- Resolution and minimum detectable object (MDO)
- Optical axis pitch
- Protection height
- Number of optical beams
- Detection distance
- Output type and signal logic
- Installation method
- Industrial environment conditions
Step 1 — Determine Object Detection Requirement
The first step is identifying the object size and detection accuracy requirement.
For smaller objects, a sensor with higher resolution is required. For larger objects or general presence detection, a wider optical axis pitch may be suitable.
Step 2 — Select Resolution and Minimum Detectable Object
Resolution describes the minimum sensing capability determined by the sensor optical structure.
The DPR-1640-NPN-NC provides:
- Resolution: 10 mm
- Minimum Detectable Object (MDO): 5–10 mm
The actual detectable object size depends on the beam structure and application conditions.
Step 3 — Select Optical Axis Pitch
Optical axis pitch refers to the distance between adjacent optical beams.
DAPPRA DPR Series Area Sensors are available with different optical axis pitch options:
- 10 mm optical axis pitch
- 20 mm optical axis pitch
- 40 mm optical axis pitch

DPR-1640-NPN-NC Engineering FAQ
The DAPPRA DPR-1640-NPN-NC is a DPR Series Industrial Area Sensor using through-beam infrared detection technology with 16 parallel infrared beams, 40 mm optical axis pitch, 10 mm resolution, 600 mm protection height and NPN NC output configuration.
An Industrial Area Sensor is a multi-beam photoelectric sensor that uses multiple light beams to create a detection area instead of relying on a single detection point. It is commonly used for object detection, machine protection and automation applications.
The DPR-1640-NPN-NC uses through-beam infrared detection with a separate emitter and receiver. The emitter sends parallel infrared beams to the receiver. When an object interrupts one or more beams, the receiver detects the change and provides the output signal.
The main factors for selecting an Area Sensor include object size requirement, resolution, minimum detectable object (MDO), optical axis pitch, protection height, beam quantity, detection distance, output type, installation method and industrial environment conditions.
Optical axis pitch is the distance between adjacent optical beams in an Area Sensor. The DPR Series includes different optical axis pitch configurations including 10 mm, 20 mm and 40 mm options.
The DPR-1640-NPN-NC has a specified resolution of 10 mm.
The specified Minimum Detectable Object (MDO) range of the DPR-1640-NPN-NC is 5–10 mm.
For DPR Series Area Sensors, protection height is calculated as (Beam Quantity − 1) × Optical Axis Pitch. For DPR-1640-NPN-NC, (16 − 1) × 40 mm equals 600 mm protection height.
The DPR-1640-NPN-NC has 16 optical beams.
The optical axis pitch of DPR-1640-NPN-NC is 40 mm.
The DPR-1640-NPN-NC provides a 600 mm protection height.
The maximum detection distance of DPR-1640-NPN-NC is 3 m.
The DPR-1640-NPN-NC operates with a DC24V ±20% power supply.
The DPR-1640-NPN-NC uses an NPN output configuration with NC (Normally Closed) signal logic.
NC means Normally Closed signal logic. For the DPR-1640-NPN-NC, the normal beam condition provides 0V output, while beam interruption results in no output.
The DPR-1640-NPN-NC response time is 0.5 ms.
The DPR-1640-NPN-NC uses an M12 cable connection.
Yes. The DPR-1640-NPN-NC is designed for industrial automation environments with IP65 protection, oil-resistant fluorosilicone coating, anti-vibration design and electromagnetic interference resistance.
The DPR-1640-NPN-NC uses wire synchronization technology.
The DPR-1640-NPN-NC uses a dual-circuit signal output design as a self-test technology to improve operational safety.
The DPR-1640-NPN-NC supports three installation methods: L1 top and bottom installation, L2 side installation and cantilever installation.
Typical applications include press machinery, injection molding machinery, stamping equipment, welding production lines, automated storage equipment, woodworking machinery and other industrial automation applications requiring multi-beam detection.
Yes. The DPR-1640-NPN-NC can be used for falling object detection applications where multi-beam infrared detection is required.
The DPR-1640-NPN-NC is supported by SIL 2 Functional Safety Certification, IEC 61508 applicable standard, CE Certification, FCC Certification and RoHS Compliance documentation.
Optical axis pitch is the distance between adjacent beams, while resolution describes the minimum detectable object capability of the sensor. A smaller pitch generally provides higher detection capability.
Yes. Because the DPR-1640-NPN-NC uses multiple parallel infrared beams, it can detect objects entering different positions within the sensing area.
DPR-1640-NPN-NC is a DAPPRA DPR Series industrial area sensor with similar application requirements to some 40mm pitch 16-beam area sensors. Product compatibility should be verified according to electrical specifications and application requirements.
