LVDS Linear Variable Displacement Sensor-Image


The LVDS Linear magnetic displacement Sensor is one of the most durable, adaptable, and lightweight linear position sensors, available in the industry, enabling highly accurate motion control and improving operation efficiency and safety. Its simple, non-contact design eliminates mechanical failure mechanisms, reducing wear and tear, improving reliability and durability, and minimizing downtime. The Linear magnetic displacement Sensor is a non-contacting sensing solution for absolute position sensing with enhanced accuracy. It senses the position of a magnet relative to the sensor in one of three


Available sensing ranges:

0 mm to 20 mm [0 in to 0.788 in]

0 mm to 30 mm [0 in to 2.95 in]

0 mm to 50 mm [0 in to 8.86 in]


The Linear variable displacement Sensor is available in both analog output (20 mm, 30 mm and 50 mm configurations) and digital output (50 mm configuration only) for use in control systems requiring an RS232-type interface with a 57.6 kbits/s baud rate.



Reliable, durable: Non-contact design reduces wear and tear, improving reliability and durability, and minimizing downtime

Easy to install: Installation takes four simple steps (1: position sensor; 2: drill holes; 3: mount sensor; 4: locate magnet actuator/make electrical connection) simplifying installation and reducing set-up costs

Rugged: As there are no moving parts within the sensor, utilizes unique packaging materials that make the sensor more resistant to vibration, shock, and extreme temperatures

Flexible:  variety of output options (analog standard and other RS232- type baud rates) are available, expanding application opportunities

Cost effective: Adaptable, non-contacting design allows customers to eliminate unnecessary connections for installation, thereby reducing installation steps, installation time, and components

Accurate: 20 mm configuration accurately measures values down to 0,04 mm, 30 mm configuration accurately measures values down to 0,05 mm, while 50 mm configuration accurately measures value down to 0,14 mm  (analog) and 0,0035 mm (digital)

Adaptable: Electronics on board allow for flexible packaging and component compatibility with existing systems

Simplifies design-in: Easy-to-configure sensor array fits virtually any linear movement path

Self-diagnostics feature: Can reduce equipment downtime by providing predictive maintenance input

IP67 and IP69K sealing: allow use in many harsh applications

Qualified for automotive grade EMI/EMC specification: Provides protection against environmental frequencies (20 mm configuration only)

RoHS-compliant materials:

Potential Application



Valve position: May be used to monitor valve position so the desired amount of liquid is delivered based on the position of the valve that is opening/closing, and how long open/closed (e.g., bottling machines, food/chemical processing, water handling equipment, etc.).

Material handling: May be used on a lifting device that moves cartons from one conveyor belt to another.

Plastic molding: May be used for injection positioning.

Cutting and slitting: May be used in paper mills to accurately control the location of the slitter before it cuts.

Wafer handling: May be used to monitor if parts are properly placed.

CNC machines: May be used to monitor tool depth and direction of travel.



Engine transmissions: May be used for gear shift position for trucks (20 mm configuration only).

Passenger bus level position: May be used for passenger bus leveling to simplify access for passengers and luggage.

Truck-mounted crane outrigger position: May be used to determine that the outriggers are fully deployed before the lifting of objects can begin.

Heavy equipment attachment identification: May be used to sense which attachments are being deployed onto heavy equipment by the strategic placement of the magnet to the sensor. The corresponding output indicates to the operator and control system which attachment is connected.

Hydraulic cylinders: May be used on non-ferrous hydraulic cylinders for non-contact stroke position (225 mm configuration only).

Marine motors: May be used for trim position on inboard



Aircraft actuators: May be used to control actuator position on multiple applications in the aircraft, helping to regulate airflow to engines and environmental systems.
