TP1-IR
The TP1-IR is a kinematic, wireless CNC touch probe for workpiece setup and tool measurement with an infrared transmission range of up to 5 m (16 ft). Wake the probe from standby by touch, spin, or tilt. Power the probe with a SAFT LS14250 battery and the receiver with 5–24 V DC.

The 0.002 mm 2σ value is repeatability, not a statement of measurement accuracy. Measuring force varies with stylus length and direction. The revision 1.0.0 datasheet characterizes repeatability with a 30 mm stylus; the instrument accepts M4 styli. For measurements with longer styli or near the maximum probing speed, discuss your accuracy requirements with DynamiTech.
In operating mode, each touch trigger has a 2 ms delay. Account for that delay, stylus length, and overtravel when setting the probing speed for the workpiece or tool. The datasheet linked in the Documentation section includes length-dependent force and typical repeatability plots.
Power and connect a standalone instrument
Use the brown VCC and white GND wires for 5–24 V DC power, the yellow TOUCH wire for the skip input, and the green READY and gray BATTERY-LOW wires for status monitoring.
With DIP switch 2 OFF, TOUCH is normally open. When the stylus is deflected, TOUCH switches VCC to the skip input after 2 ms. With DIP switch 2 ON, TOUCH is normally closed and switches VCC to the skip input at rest. These are switchable output functions; set the one that matches your control. See the wiring and DIP switch settings.
Choose it for the right application
Use this model when you need a wireless infrared touch probe with PNP switching outputs. It does not record axis positions or transmit without line of sight. If you need operation above 2 m/min, repeatability better than 0.002 mm, or strain-gauge sensing, review the requirements with us before selecting it.
Compare the axial TP1-W-A and radial TP1-W-R in the connection overview.
Program IR transmission behavior
P1 sets the IR LED power, P2 the standby time, and P3 the switch-on method; P4 counts touches. You program them with the stylus; no software is required. The Control Panel shows the P1 and P3 values.
For spin switch-on, set P3 = 2 with two short touches and one long touch.
The green LED then flashes twice to confirm. Short touches last under 0.5 s, long touches over 1 s; a long touch alone keeps the current value. See the probe settings and the programming guide.
Before a measurement, wake the probe, check the READY state, and allow for the signal delay required by the entire setup. The READY state readback confirms the operating mode; it is not a measurement of repeatability or accuracy.
