What Is a Safety Light Curtain?
A safety light curtain is a non-contact machine protection device that uses multiple infrared beams to create a defined detection area. When an object or person interrupts the beams, the sensor detects the interruption and sends an output signal to the machine control system.
Unlike a single-point photoelectric sensor, a safety light curtain creates multiple detection points across a defined protection height, allowing it to monitor a larger access area around industrial machinery.
The DAPPRA DPR Series uses through-beam infrared detection with a separate emitter and receiver to create the detection area.
What Is a Safety Light Curtain Used For?
A safety light curtain is used to monitor access to hazardous areas around industrial machinery without requiring physical contact.
Typical applications include:
- Automated production lines
- Conveyor systems
- CNC machines
- Press machines
- Press brake equipment
- Injection molding machinery
- Cutting equipment
- Welding lines
- Automated assembly equipment
- Material handling equipment
- Industrial machinery protection
The DPR-1040-NPN-NC provides a 360 mm protection height using 10 infrared optical beams with a 40 mm optical axis pitch.
What Is a Safety Light Curtain Safety Sensor?
A safety light curtain is a non-contact safety sensor that uses multiple infrared beams to detect objects or people entering a protected area.
The DPR-1040-NPN-NC consists of an emitter and receiver. The emitter generates parallel infrared beams, while the receiver monitors whether the beams are continuously received.
When one or more beams are interrupted, the receiver detects the interruption and changes the output state according to the NPN NC signal logic.
Safety Light Curtain vs Standard Photoelectric Sensor
A standard photoelectric sensor generally detects an object at a defined sensing point or sensing area. A safety light curtain uses multiple infrared beams arranged across a defined protection height to monitor access to a larger machine area.
The DPR-1040-NPN-NC uses a separate emitter and receiver to create a multi-beam infrared detection field with 10 optical beams and a 360 mm protection height.
How Does a Safety Light Curtain Work?
Through-Beam Infrared Detection
The DPR-1040-NPN-NC uses an infrared LED emitter and receiver to form 10 parallel infrared beams.
The emitter transmits infrared light toward the receiver. When an object or person enters the detection area and interrupts one or more beams, the receiver detects the interruption and switches the output state.
When all beams are clear, the receiver detects continuous infrared transmission and maintains the normal output condition.
Detection Logic
- Beam Clear → Output ON
- Beam Interrupted → Output OFF
Safety Light Curtain Types
Safety light curtains can be configured according to optical axis pitch, protection height, output configuration and signal logic.
Common configurations include:
- Different optical axis pitch configurations
- Different optical beam quantities
- Different protection height configurations
- NPN or PNP output configurations
- Normally Closed (NC) or Normally Open (NO) signal logic
- Different installation configurations
The DAPPRA DPR Series uses a through-beam infrared detection structure with a separate emitter and receiver.

Protection Height vs Total Height
Protection height and total height describe different physical dimensions of the DPR-1040-NPN-NC.
Protection height is the effective height of the optical detection field, measured from the center of the first optical beam to the center of the last optical beam.
Total height is the complete physical height of the sensor.
For the DPR-1040-NPN-NC:
| Dimension | Value |
|---|---|
| Protection Height | 360 mm |
| Total Height | 446 mm |
The difference between these dimensions accounts for the physical sections of the sensor outside the effective optical beam field.
Optical Axis Pitch vs Resolution
Optical axis pitch and resolution describe different characteristics of the sensor.
Optical axis pitch is the distance between the centers of adjacent optical beams.
Resolution is the specified detection capability of the sensor.
For the DPR-1040-NPN-NC:
| Parameter | Value |
|---|---|
| Optical Axis Pitch | 40 mm |
| Resolution | 10 mm |
The DPR-1040-NPN-NC therefore combines a 40 mm optical axis pitch with a specified 10 mm resolution.
What Does NPN NC Mean?
NPN refers to the transistor output configuration of the sensor.
NC means Normally Closed signal logic.
For the DPR-1040-NPN-NC, the output is ON when the infrared detection field is clear. When a detection beam is interrupted, the output changes to OFF.

FAQ
The DPR-1040-NPN-NC is a DAPPRA Safety Light Curtain Area Sensor with 10 optical beams, 40 mm optical axis pitch and 360 mm protection height. It uses NPN normally closed (NC) signal logic for industrial machine protection and automation applications.
The DPR-1040-NPN-NC has 10 optical beams.
The optical axis pitch of the DPR-1040-NPN-NC is 40 mm.
The protection height of the DPR-1040-NPN-NC is 360 mm, measured from the center of the first optical beam to the center of the last optical beam.
The total height of the DPR-1040-NPN-NC is 446 mm.
The specified detection distance of the DPR-1040-NPN-NC is 0.1–3 m.
The DPR-1040-NPN-NC uses NPN output with NC (Normally Closed) signal logic.
The specified response speed of the DPR-1040-NPN-NC is 0.5 ms.
The DPR-1040-NPN-NC operates at DC24V.
The DPR-1040-NPN-NC has an IP65 protection rating.
The emitter uses an M12 3-pin connector, and the receiver uses an M12 4-pin connector.
The supplied connection cable length is 2 m.
The DPR-1040-NPN-NC is supplied with SIL 2, CE, FCC and RoHS certification. The safety specification references IEC 61508.
The DPR Series supports top and bottom mounting, side mounting and cantilever mounting.
When an infrared beam is interrupted, the receiver detects the interruption and the NPN NC output changes to OFF. When all beams are clear, the output is ON.
