INDUCTIVE SENSORS

INDUCTIVE SENSORS

Product catalog summary

Applications
Inductive sensors are utilized in environments with oil, dust, liquids, and vibrations, commonly found in machine tools, textile machines, transport systems, packaging equipment, and the automotive industry for automation solutions.

Standardized Sensing Plate
The sensing plate, as per EN60947-5-2, is a square steel plate used to compare sensing distances. Its size should match the sensor's active surface diameter, with larger plates not increasing the nominal intervention distance.

Intervention Distances

Nominal Intervention Distance (Sn): Considers temperature and voltage variations.
Real Intervention Distance (Sr): Measured at nominal conditions, with 0.9Sn ≤ Sr ≤ 1.1Sn.
Useful Intervention Distance (Su): Measured within specified limits, with 0.9Sr ≤ Su ≤ 1.1Sr.

Tightening Torques
Ensure specified tightening torques are not exceeded during installation to prevent mechanical damage.

Working Principle
Inductive sensors generate an alternating inductive field that changes when a metallic object enters, altering the oscillator state and controlling an external load. They offer advantages over mechanical switches, such as unlimited lifespan and no maintenance.

Sensor Versions

Version N: Non-amplified, two-wire DC sensors for electronic circuits, with ATEX approval.
Version B: Two-wire amplified DC sensors for programmable controllers.
Version C: Three or four-wire amplified DC sensors, protected against short circuits and polarity issues.
Version A: Two-wire AC sensors with thyristor output amplifier, compatible with PLC units.

Wiring Diagrams
Various configurations ensure compatibility with programmable controllers and protection against voltage transients.

Power Supply Suggestions
Supply voltage should match sensor characteristics, using a transformer with secondary voltage lower than required direct voltage, and filtering with at least 470 µF per 200 mA is recommended.

General Characteristics
Ring sensors detect metallic objects within the ring, suitable for small metal objects and continuous metal wires. Available internal diameters range from 5 to 100 mm.

Use with Delayed Amplifiers
Ring sensors can be used with programmable ALTP series delayed amplifiers for detecting small, fast-moving objects, allowing adjustable delay times.

Effects of Nearby Metals
Maintain a suitable distance between the sensor and metallic objects to avoid interference.

Use of Sensor
Maintain a distance equal to the sensor's width between objects passing through it. Adhere to recommended minimum distances when installing multiple sensors.

Selection of Ring Sensor
Select based on the minimum hole diameter needed for control, ensuring sensitivity adjustments within normal parameters.

Sensitivity Adjustment
Adjust sensitivity after installation, considering nearby metal masses. Sensitivity increases by turning the trimmer clockwise.

Switching Frequency
Depends on the delayed impulse time, with a formula provided for calculation. Non-amplified NAMUR models can be paired with an ALTP amplifier for adjustable delay times.

Technical Characteristics
Inductive ring sensors are available in various models with different technical specifications, designed for non-flush mounting with adjustable sensitivity and delay features.
