Introduction

The LX series of cable displacement transducers are designed for linear displacement measurement in industrial environments over strokes from 0 to 1250 mm. With a robust, compact and economical thermoplastic design, the LX series of cable sensors is ideally suited for OEM projects.

2 models are available: LX-PA with analogue output and LX-EP with digital output. Eleven measuring ranges are available, from 50mm to 1250mm.

Installation

The cable is directly or indirectly linked to the displacement to be measured, which allows for non-normal or non-linear displacement. The measurement can be offset by cable extensions. The cable sensor is not necessarily aligned with the displacement.

The standard terminal block can be replaced by an optional connector or cable. The cable end can be customised to facilitate integration with the desired application.

Mounting accessories are also available.

Applications

The LX series sensors are recommended for :

OEM development projects
integration in limited spaces, applications that require a very small sensor
Automotive, speed and acceleration testing
suspension travel measurements
any other industrial application (test bench, lifting, handling) or robotics
