These units are completely self-contained, and house a field generator, amplifier, and other necessary circuitry to accomplish electronic switching.The units are all solid state and have no moving parts that can wear out. The electronic switches are not susceptible to contact contamination, contact erosion, or material transfer as are mechanical switches.The switching is insensitive to vibration, and is positive without chatter, regardles of how slowly the target approaches or recedes from the sensor.The oscillator resonant circuit, located in the proximity switch, uses an open core coil to help produce a concentrated high frequency electro-magnetic field, which emerges from the active surface of the sensor. If a metal target enters this field, eddy currents are induced. The floating induced eddy current draws energy from the LC circuit . The load on the oscillator circuit evokes a decrease in the oscillating amplitude. The oscillator is attenuated.The decrease of the oscillating amplitude is converted into an electrical signal by the electronic circuit, which leads to a change of switching state of the proximity switch.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">When the electric conductive material is removed from the inductive field, the pulse amplitude increases and via the electronic circuit the original switching position is recreated.
