METROL Tool Setting Probe H4A-12-133S

Buy online your METROL Tool Setting Probe H4A-12-133S from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The METROL H4A-12-133S tool setting probe is designed for automatic tool length measurement and tool breakage detection on CNC machine tools. Installed on the machine table or a fixed mounting bracket, it provides a precise electrical contact signal to the CNC control, allowing tool offsets to be updated automatically during measurement cycles. It is an ideal replacement unit or spare part for CNC machining centers and milling machines.

This compact, high-precision contact sensor delivers highly repeatable triggering whenever the tool tip touches the sensing surface. The output signal enables the CNC control to execute automatic tool touch-off, length measurement, and tool breakage detection cycles, improving machining accuracy while reducing manual setup time and operator intervention.

The METROL H4A-12-133S integrates easily with the tool setting routines of major CNC control systems, including FANUC, SIEMENS, MITSUBISHI, and HEIDENHAIN. Replacing an identical probe is typically straightforward, allowing existing wiring, machine parameters, and mounting hardware to be retained. This model replaces the previous H4A-12-21 version, providing a direct replacement solution for compatible installations.

Designed for continuous operation in demanding industrial environments, the probe offers excellent repeatability even in the presence of coolant and metal chips. It helps prevent machining errors by detecting broken or worn tools before they affect production quality, contributing to improved machine productivity and reduced scrap.

Each unit can be functionally tested by qualified engineers on dedicated CNC test equipment to verify switching performance and signal stability before shipment. Sensitive contact surfaces and connectors are protected during transport, and every product is covered by the Cnc-shopping warranty. Repair, exchange, and obsolete part sourcing services may also be available to help extend the operating life of legacy CNC equipment.

Frequently asked questions about H4A-12-133S:

Is the METROL H4A-12-133S compatible with my CNC control?
The probe provides a simple contact signal used by common tool setter macros on many CNC controls. Verify the wiring convention and input type in your machine manual and match them to the H4A-12-133S variant on your machine.

Where is this probe typically mounted on the machine?
It is usually fixed on the machine table or a dedicated bracket in the tool measurement position defined by the OEM. Reusing the existing bracket and location is recommended when replacing the same model.

What symptoms indicate that my current tool setter needs replacement?
Inconsistent triggering, no signal when the tool makes contact, or sporadic alarms during touch-off cycles are common signs. Once cabling is confirmed, replacing the worn probe often restores reliable tool length measurement.

Can I order a tested or refurbished unit?
Depending on inventory, Cnc-shopping can supply a tested unit and may offer a refurbished unit or exchange option after inspection. Contact our team for current availability and lead times.

What should I confirm before ordering this replacement unit?
Check the full model code on your existing probe, the mounting style and the wiring convention defined in the machine documentation. Matching the exact code helps ensure a true drop-in replacement without changes to brackets or I/O.
