WENTAO High-Precision Touch Trigger Probe for CNC Machines

WENTAO T-40A High-Precision Infrared Workpiece Probe

The WENTAO T-40A is a premium optical machine workpiece probe specifically engineered for medium and small-sized machining centers, as well as small-scale multi-tasking machine tools. Utilizing a highly stable 3-point trigger design and reliable infrared optical transmission, it automates workpiece alignment, edge-finding, and in-process dimensional inspections. It seamlessly transmits precise real-time trigger signals to your CNC system via the T-50A receiver, securing maximum processing accuracy and dramatically cutting down machine setup times.

Key Features & Advantages

• Stable 3-Point Trigger Structure: Employs a mechanical-electronic hybrid trigger mechanism. When the stylus deflects, it instantly transmits trigger signals to obtain accurate machine coordinates.

• Exceptional Repetitive Accuracy: Delivers a superb single-directional repeatability of $1.00\mu m$ (tested with a 50mm stylus at a standard speed of 480mm/min).

• Precise Self-Resetting (< $1\mu m$): The precision-engineered mechanical return mechanism guarantees that the stylus automatically returns to its initial position with a relocation error of less than $1\mu m$, enabling highly reliable continuous measuring operations.

• Superior Anti-Interference Performance: Works in harmony with the T-50A receiver using a modulated optical transmission mode. This specialized system provides highly robust resistance against optical interference, accidental triggers, and heavy machine vibration.

• Highly Configurable Modes & Filters: Supports customized user adjustments including optical power levels, configurable turn-on/turn-off methods (optical trigger or time-out delay), and an optional 10ms enhanced trigger filter to resist intense physical shocks.

• Ultra-Low Power Optimization: Features adjustable optical transmission power. For compact workspaces, switching to ultra-low power mode significantly extends battery life when powered by two $1/2$ AA 3.6V Lithium Thionyl Chloride (LTC) batteries.

• Severe Environment Defense: Certified with a high-durability IPX8 protection rating alongside an IK01 impact-resistant glass window, shielding inner optical systems from cutting fluids, oils, and metal fragments.
