The Blade25 Position Transducer is a solid-state device, using induction technology to monitor the position of a metallic object ('activator') that is mounted to or machined as part of the moving part of the application.
With a constant air gap between the moving part and the position transducer, mechanical wear of the transducer is eliminated providing excellent long-term reliability even in the most extreme operating environments.
The Blade25 position transducer houses two inductive coils that determine the position of the metallic activator, and has been designed to allow measurement of both linear (up to 25mm) and angular rotation (up to 90° approx) position. It is also possible to monitor non-uniform movement provided that the movement is repeatable.
The position transducer is supplied with 'BladeCOM' calibration software to allow simple reconfiguration of the device. The operational range, switch points, output modes and other advanced parameters can be set from within the software, with the sensor functionality shown via a real-time monitoring and diagnostics display.
- Suitable for Linear (25mm), Angular (90º) or Non-Uniform Position Monitoring
- IP67 Protected - Suitable for Submersion
- Suitable for dusty, moist and high vibration environments
- Not susceptible to presence of magnetic fields
- Multiple Output Modes - Analogue; PWM; Serial; Switch
- Free BladeCOM Configuration Software
- Excellent Long-term reliability (unmatched by contacting potentiometers, LVDTs etc)
If the Blade25 position transducer is not suitable for your application in its current form we can develop a custom variant of the transducer to perfectly match the requirements of your application. In most cases it is possible to re-house the standard electronics with a custom mechanical packaging solution, reducing the overall position transducer development cost.

The Blade25 Demo Kit is specifically designed for the customer to evaluate our non contact measurement position transducer technology.
The Blade25 transducer is mounted to an easy to use rig, which demonstrates rotary and linear measurement. When powered up via the 9v battery, an RS232 compatible output, plus an analogue and PWM output are generated.
The Demo Kit Includes...- Blade25 Position Transducer
- Angular & Linear Movement Rig
- 3 x Activators (different materials)
- Wiring loom with all necessary connectors
- Calibration Software
- 9V Battery
- Robust Carry Case
The demo rig allows both linear and angular movement
The Blade25 position transducer is suitable for a wide range of linear and angular movement applications and is especially suited to harsh operating environments. Some example applications are shown below, both for the standard Blade25 and for custom variants using the same measurement technology.
-
Pedal Position Monitoring
In this application the Blade25 is mounted to the pedal base plate, with the activator mounted to the moving pedal. The activator moves across the face of the sensor in an arc movement, with the sensor programmed to give the full scale output over ±30° (total pedal rotational movement).

Sliding Door Control (Soft-stop)
In this application the Blade25 position transducer is used to control closing of an electronically-operated sliding door. The sensor monitors the left-most 25mm potion of the door via an integral activator and feeds back the position in real-time to the door's controller, allowing for soft-stop operation and system feedback when the door is in the 'fully-closed' position.

Suspension Rocker Position Feedback
This application is based on the standard suspension rocker often used on open-wheel race cars. The Blade25 position transducer is mounted to the rocker pivot. The activator is mounted to the face of the rocker and moves across the sensor in an arc. The sensor is programmed to give full-scale output over the 15° measurement range.

Gearbox Shift Fork Position (Custom Transducer)
This custom position transducer uses the Blade25's core electronics and operating principle, in a custom configuration suitable for an industrial gearbox. The position transducer is mounted through the transmission housing; the activator is machined into the top of the shift fork and moves across the face of the sensor when the operator changes gear.
