The IFM DP4402 pulse stretcher is an IO-Link signal conditioner designed to extend or delay short digital pulses so that they can be reliably detected by control systems. It provides decentralized pulse processing and switching functionality in a compact IP69K-rated device. It is suitable for high-speed machine signals, object detection and industrial automation applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
DP4402 is designed to make short-duration machine pulses easier for automation systems to detect and process. It can extend or delay pulses according to application requirements. This is useful when sensors generate signals that are too short for downstream control equipment to reliably recognize.
The device processes digital input pulses and provides IO-Link communication together with switching outputs. Pulse extension or delay improves signal availability to connected control equipment. Its IP69K protection supports use in demanding industrial installations where robust environmental protection is required.
DP4402 provides a simple solution for pulse-processing problems without requiring complex PLC programming. It can improve the reliability of short sensor signals and simplify decentralized machine control. Its IO-Link capability also allows convenient parameterization and diagnostics.
