Pin Functions
Pin 1; LC
The resonant circuit of the proximity switch is connected between LC and ground.
Pin 2; R
A resistor between this pin and ground sets the current in the oscillator circuit. The greater the
value of the resistor, the smaller is the current feed from the oscillator into the resonant circuit
and the greater therefore is the switching distance. The greater the Q of the resonant circuit,
the greater is the value of the distance resistor necessary for setting a certain switching
distance.
Pin 4; C
C
provided with a series RC element (R
element on this pin will also prevent any erroneous pulses on the output when the supply
voltage is turned on (see application circuit 1).
Pin 5; R
Depending on the status of the circuit, R
(open collector). If the distance resistance (see R
distance hysteresis can be set by means of R
in series with R
or made high-impedance (see application circuit 1).
Pin 6; SC
SC serves for short-circuit sensing in the output circuit that is to be protected. The current can
be sensed referred to ground or V
output circuit. For a voltage drop 0.3 V across V
are turned off after the turn-OFF delay (brief glitches on the outputs or the charging of line
capacitances therefore do not trigger the short-circuit protection). After a pause about 200
times the turn-off delay, the outputs turn-ON again. If the short-circuit is still present, the turn-
OFF cycle will start up anew.
