The DAPPRA DPF Series is a press machine safety light curtain designed for stamping, cutting, extrusion and other vibration-heavy industrial equipment. Signal detection and output are handled through a dedicated controller.
The DPF Series uses a 50 × 35 mm aluminum alloy housing with an internal vibration-resistant structure, providing reliable detection in high-vibration environments. It supports 10 / 20 / 40 mm optical-axis pitch, NPN / PNP output and a wide range of controller and mounting options.
The DAPPRA DPF Series is a press machine safety light curtain series primarily used for stamping machine safety protection. The product adopts a controller-based signal detection design, with the controller handling light curtain signal detection and relay output.
The DPF Series operates on AC110–220V or AC380V through the controller, and the internal components use imported original parts for stable performance. The vibration-resistant aluminum alloy housing and complete self-checking functions make it suitable for pressing, cutting, extrusion and other vibration equipment.
The series provides 10 mm, 20 mm and 40 mm optical-axis pitch configurations, with beam quantities from 4 up to 100 and multiple protection heights and total heights for different industrial sensing and protection requirements.
Engineered for press machines, stamping equipment and other vibration-heavy industrial applications.
The DPF Series works with a dedicated controller for signal detection and relay output. Two controller configurations are available according to voltage environment and installation space.
Compact built-in controller designed for installation inside the machine cabinet. Suitable for AC110–220V environments.
External controller with an enhanced enclosure and improved functions, working voltage AC220V. A 380V version is available on request for different industrial power environments.
One controller can be configured to manage multiple DPF sensor sets, enabling multi-face protection such as one-to-two or one-to-three configurations.
Select the appropriate DPF model according to the optical-axis pitch, beam quantity and output type. Controllers are selected separately as optional accessories.
