Product Description

LMDS  Linear Magnetic Displacement Sensor
Description
The 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 75 mm [0 in to 2.95 in]
• 0 mm to 225 mm [0 in to 8.86 in]
These sensors uses an array of MR ( magnetoresistive) sensors to accurately and reliably determine the position of a magnet attached to a moving object so that the object's position can be determined or controlled. The MR array measures the output of the MR sensors mounted along the magnet's direction of travel. The output and the MR sensor sequence determine the nearest pair of MR sensors to the center of the magnet location. The output of these two MR sensors is then used to determine the position of the magnet between them. The Linear magnetic displacement Sensor is available in both analog output (20 mm, 75 mm and 225 mm configurations) and digital output (225 mm configuration only) for use in control systems requiring an RS232-type interface with a 57.6 kbits/s baud rate.
 
FEATURES AND BENEFITS
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: Air gap of up to 8,5 ±1,0 mm  between sensor and magnet expands application opportunities; 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, 75 mm configuration accurately measures values down to 0,05 mm, while 225 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) 
 
Applications
INDUSTRIAL
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.
 
TRANSPORTATION
Engine transmissions: May be used for gear shift position for trucks (30 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
AEROSPACE
Aircraft actuators: May be used to control actuator position on multiple applications in the aircraft, helping to regulate airflow to engines and environmental systems.
