Optical Detection Structure
The DPF-1220-NPN-NC uses separate EMITTER and RECEIVER units to create a parallel infrared detection field. The signal is transmitted to the controller, which performs detection and provides relay output.
The 12 optical beams are arranged with a 20 mm optical-axis pitch, providing a 220 mm protection height.
EMITTER → Parallel Infrared Beams → RECEIVER → CONTROLLER → RELAY OUTPUT
When an object or person interrupts the infrared beam path, the receiver detects the change in the optical field and transmits the signal to the controller, which provides the corresponding NPN NC relay output.
Area Sensor vs Safety Light Curtain
The terms Area Sensor and Safety Light Curtain are commonly used in industrial automation to describe multi-beam photoelectric detection products, but they may represent different technical and safety requirements depending on the application.
An Industrial Area Sensor is generally used for multi-beam detection of personnel, objects, access areas and machine processes.
A Safety Light Curtain is typically associated with machine protection and applications where specific functional-safety requirements and applicable safety standards need to be considered.
The DPF-1220-NPN-NC is designed as a Press Machine Safety Light Curtain for stamping, cutting and extrusion equipment, using a controller for signal detection and relay output. The appropriate safety configuration and integration should be determined according to the machine risk assessment and applicable safety requirements.

How are the EMITTER and RECEIVER connected?
+
The DPF Series uses separate EMITTER and RECEIVER units with wired synchronization. The signal is transmitted to the controller, which handles detection and provides relay output to the machine control circuit.
How do I choose the correct DPF model?
+
Select the required optical-axis pitch and protection height according to the press machine opening and detection requirements, then confirm the controller model, output configuration and mounting brackets. For model selection assistance, provide the required protection height, protection distance, controller voltage and machine structure to DAPPRA.
