TX2 with Novotechnik clamps | Linear position sensor
- Manufacturer: Novotechnik
He TX2 with clamps Novotechnik it's a potentiometric linear position sensor Designed to measure the absolute and direct displacement of mechanisms and moving elements. It is available with defined electrical travels of 25, 50, 75, 100, 150, 200, 250 and 300 mm and uses a resistive track made of conductive plastic that works as a voltage divider.

Applications of the TX2 linear position sensor with clamps
The adjustable clamp mounting allows the TX2 to be used in applications where linear position or stroke measurement is required, while maintaining freedom to define the sensor body fixing points.
Industrial machinery and automation
- Absolute measurement of position and displacement.
- Linear mechanism stroke control.
- Position feedback in machines and automatic systems.
- Motion measurement in actuators and mechanical assemblies.
- Installations in confined spaces thanks to the Ø 16 mm body.
Test benches and measuring systems
- Position recording during mechanical tests.
- Simultaneous measurement of displacement with force, pressure, torque, or other variables.
- Repetitive motion tests and operating cycles.
- Verification of races and final positions.
Demanding industrial environments
The IP67 protection and the construction with anodized aluminum housing and stainless steel stem allow the TX2 to be used in applications exposed to dust, humidity, oil and dirt, always respecting the assembly conditions indicated by the manufacturer.
Mounting using adjustable clamps
The mechanical execution 717 Identify the TX2 with clamp mounting. Supplied two fixing clamps and two M5x20 screws.
The recommended distance between clamps depends on the selected travel:
- 25 mm: 30 mm.
- 50 mm: 50 mm.
- 75 mm: 70 mm.
- 100 mm: 90 mm.
- 150 mm: 140 mm.
- 200 mm: 190 mm.
- 250 mm: 240 mm.
- 300 mm: 290 mm.
The drive stem is rotatable, made of 1.4305 / AISI 303 stainless steel and has an M5 external thread.
When the application may transmit lateral forces or there is misalignment between the sensor shaft and the moving element, Novotechnik recommends using a suitable coupling to avoid lateral loads on the stem.
Potentiometric output and connection to control systems
The TX2 is a linear potentiometric transducer. The resistive element made of conductive plastic acts as a voltage divider and generates a signal proportional to the position of the stem.
It does not include a standard industrial output of 0–10 V or 4–20 mA. When the control system requires one of these signals, a compatible signal conditioner can be used to power the potentiometer and convert the position signal.
According to the path, the nominal resistance value is 1 to 12 kΩ. The recommended current on the cursor should be kept at ≤ 1 µA and the maximum permissible voltage is 42 VDC.
This technology provides an absolute signal: after a power disconnection, the position is obtained directly from the resistive value when power is restored to the circuit, without the need to count pulses or perform a reference search.
M8x1 connector or 2-meter PUR cable
The TX2 with clamps is available with two electrical connection options:
- Code 101: M8x1 3-pole radial connector.
- Code 202: 2m radial shielded PUR cable.
Connection assignment
- Connection 1: pin 1 / BN – brown.
- Connection 4, signal output: pin 4 / WH – white.
- Connection 3: pin 3 / GN – green.
The signal increases when the stem is extended when the positive supply is connected to connection 3 and decreases when the positive is applied to connection 1. The position signal is obtained at connection 4.

Frequently asked questions about the TX2 with clamps
What tours are available?
The TX2 series with clamps is available with defined electrical travels of 25, 50, 75, 100, 150, 200, 250 and 300 mm.
Does the TX2 have a 0–10 V or 4–20 mA output?
Not directly. The TX2 is a potentiometric sensor that functions as a voltage divider. If a standardized 0–10 V or 4–20 mA signal is required, a compatible signal conditioner must be used.
What is the difference between the TX2 with clamps and the TX2 with ball joints?
Both use the same potentiometric principle and are available up to 300 mm. This version secures the body using two adjustable clamps. The version TX2 with ball heads It uses articulated heads that allow compensation for angular misalignments between mounting points.
