AVT2706 A

The system works perfectly wherever a non-contact position control is necessary. The principle of work is simple - moving a piece of magnetic material close to the resonant circuit (eg steel) causes the resonant circuit to become unbalanced. This change is detected and passed to the executive level.
In the AVT 2706, the sensor coil is hidden in the half of the ferrite cup. This is to limit the field of view of the sensor to one direction. At the output of the system, an open-collector transistor was used. It allows to attach any executive system, eg a relay or a shining diode. The entire system is small, easy to assemble and start up

The device is especially recommended for electronics-automation specialists and experimenters

Selected sensor parameters:

• operating zone - 1-10 mm from the coil face
• ceramic filter 455 kHz
• open collector output (100 mA)
• power supply - 12 V
• printed circuit board and documentation included
