DLP25 Hard-Wired CNC Touch Probe for Workpiece Setup

DLP25 hard-wired CNC touch probe supports workpiece setup and contact measurement through a 5 m oil-resistant cable. It features repeatability below 1 μm (2σ) under specified test conditions, an SUS 316 housing, IP68 sealing and ±X, ±Y, ±Z triggering.

DLP25 is a compact hard-wired CNC touch probe designed for workpiece setup, datum setting and contact measurement on CNC machine tools. Unlike optical or radio probing systems, its trigger signal is transmitted through a cable, making it suitable for installations where a wired connection can be routed safely and protected from machine movement.

The probe is specified with repeatability below 1 μm (2σ), measured using a 50 mm stylus at probing speeds of 50–200 mm/min. It supports ±X, ±Y and ±Z triggering, with an XY trigger force of 0.5–0.9 N and a Z trigger force of 6.2 N. The SUS 316 stainless steel housing and IP68 sealing are intended for demanding machine-tool environments.

The published configuration specifies a 5 m oil-resistant, four-core cable. The DLP25 is intended for integration with suitable probe inputs or interface hardware and controller macros, subject to machine-specific compatibility checks. Qidu provides installation and application support for selecting and implementing the system.

What is the DLP25 hard-wired CNC touch probe used for?

The DLP25 is designed for workpiece setup, datum establishment, positioning and contact measurement on CNC machine tools. When integrated with suitable controller inputs and probing software, it can support programmed measurement operations.
How does the DLP25 communicate with the CNC controller?

The DLP25 uses a wired electrical connection rather than infrared or radio transmission. Its cable carries probe signals to an appropriate machine input or interface system. The required electrical configuration must be confirmed for each CNC controller.
What is the repeatability of the DLP25 CNC touch probe?

The specified repeatability is below 1 μm (2σ), measured using a 50 mm stylus at probing speeds of 50–200 mm/min. Actual measurement results depend on stylus setup, calibration, machine conditions and measurement procedures.
What is the difference between a hard-wired CNC probe and a wireless probe?

A hard-wired probe sends its trigger signal through a physical cable, while optical and radio probes use wireless communication systems. Wired probes can be appropriate for fixed installations where cable routing is manageable. Wireless probes offer greater flexibility when cabling would interfere with machine movement.
Is the DLP25 suitable for CNC machining environments?

The DLP25 has an SUS 316 stainless steel housing, IP68 protection and an oil-resistant cable. These specified characteristics make it suitable for consideration in machining environments, provided the installation and operating conditions remain within its rated limits.
Does the DLP25 require a separate wireless receiver?

No optical or radio receiver is needed for its hard-wired transmission method. However, depending on the machine controller and electrical signal requirements, a compatible probe interface may still be necessary.
Can the DLP25 work with FANUC or Siemens CNC machines?

Qidu provides technical support for integration with major CNC control platforms. However, compatibility with a particular FANUC, Siemens or other controller requires confirmation of electrical inputs, wiring, measurement macros and installation requirements before ordering.
