DESCRIPTION
 |
|
The AMS8170 series are hybrid
circuits dedicated to tubular inductive proximity detectors,
especially for small diameter hollow stud constructions.
The module consists of a proximity detector IC with a PNP
output buffer for NC and NO applications. A part of the multiple
protection functions and the status indicator (LED) are realised
with discrete elements. All these components are assembled
by using hybrid thickfilm technology (ASIC-on-Hybrid) combined
with surface mounted devices.
By adding a coil with a potcore and a distance resistor the
AMS8170 series works as a complete proximity switch.
AMS8176 Proximity switch hybrid for switches
with 4 or M6 diameter.
AMS8177 Proximity switch hybrid for switches
with M6 or M8-M12 diameter. |
