LTL POSITION SENSOR

LTL POSITION SENSOR

The LTL position sensor uses an array of Hall sensors to measure positions

without contact, thanks to the presence of a magnet inside the cylinder.

It uses a smart algorithm to adapt dynamically to the magnets during

operation, so that the output signal is always linear and reproducible.

This technology allows the position sensor to adapt dynamically to

changes in the intensity of the magnetic field connected with ageing of

the magnet and the different operating temperatures.

A magnetic field intensity of between 2 and 15 mT is required for correct

operation.

The LTL can be set by means of a TEACH-PAD capacitive button that

allows rapid actuation of the position sensor and adaptation to the user’s

requirements. Just press slightly with the fingers to:

• select an output current (4-20 mA) or output voltage (0-10 V);

• establish the desired measuring range;

• reset the position sensor to the factory setting.

The button is designed to prevent unintentional changes to the

parameters.

The position sensor is out of the measuring range when:

• the yellow light is off; and

• the voltage signal is 11V (range 0-10V) or the current 3 mA

(range 4-20 mA).

LED1 (operating light) comes on when the piston is in the measuring

range:

• yellow on - optimal signal power;

• yellow on and red flashing - signal power not optimal.

LED2 tells you which analogue output is active:

• green – voltage analogue output;

• blue – current analogue output.

The position sensor is secured by means of brackets near one of the

actuator T-slots.

The LTL position sensor is applied to ISO 15552 type A cylinders, and

electric cylinders serie ELEKTRO ISO 15552.
