EX Photoelectric Sensors Ultra-slim Photoelectric Sensor The EX series is one of the-color indicator on the sensor head allows for quick determination of the sensor state. We consider the conversion from a 12V input to a 5V output for driving logic circuitry. The 3R load allows a clear demonstration of the current limiting 30463 action.

Retroreflective type mm Diffuse reflective type Setting distance: The charge current is modified by a voltage at the Ipk-sense pin to shorten the charge time and so reduce 3063 maximum duty cycle.

This is a straightforward dc-dc converter that produces an output voltage less than the input voltage. This is needed to prevent the set and reset inputs of the flip flop being active at the same time, and so causing the simulator to choke.

Try Findchips PRO for ex Xoutgate ensures that the flip flop output signal is turned off when the feedback control signal is off. Examination of the red oscillator trace shows that the charge time is shorter during a gated on period.

30463 type CX EX 2 m 6. It comes in an 8 pin DIP and requires only a handful of additional components. 340663 a large filter capacitor, this signal typically spans a number of oscillator cycles. The enclosed replaceable basic switch is accessible when the cover is removed.

The EX series solves all of the difficulties associated with fiber sensors, such as: For designing dc-dc converters, the datasheets have a table of formulas that may be used, however this should not be a replacement for understanding of the circuit operation as the designs may need to be tweaked for a variety of reasons.


The oscillator-source block generates the timing capacitor current in response to the output of the comparator. During the charging period the flip flop is set when the voltage at the feedback input pin 5 falls below 1.

The focus of this page is to study the behaviour of some switching power circuits using the MC The latter can be obtained using the method described in the gEDA setup page.

This has been tested using a number of test circuits including the buck, boost and buck-boost example configurations shown in the datasheets. With its wide bandwidth and high linearity, the INA- is suitable as a driver amplifier for various applications.

This chip has been around for quite a while and is very inexpensive. The following plot shows a detailed portion of the resulting simulation in ngspice.

Previous 1 2 While it is no replacement for measurements on hardware, it can provide quite good behavioural modelling of complex circuits, allowing many errors and problems to be corrected before the hardware is built.

As well as the spreadsheet provided here, more comprehensive resources can be found on the web, see in particular references 4 and 5. EX series EX series Single-point tightening! To improve performance this was replaced with a controlled hysteresis switch similar to that used in the AEi model.

Some of the difference may be in the filter capacitor ESR and inductor series resistance which we have assumed as zero. A set-reset flip flop is held in the reset state during the discharge cycle, causing the output switching transistor to turn off.

Practical circuits and problems experienced. This provides a form of current limiting. The signal “oscillator” provides a pulse that goes low when the capacitor is being discharged. The differentiator formed by Cdelay and Rdelay along with the squaring comparators provide two short pulses, one following the leading edge of the oscillator pulse delayminus and one following the trailing edge delayplus.


The model is different to the AEi model but makes use of some information about MC behaviour. Mountable with M3 screws! The control functions provided consist simply of a comparator that gives hysteretic or bang-bang control.

The yellow plot is the feedback comparator gating signal that turns the switching process on and off.

EXsubjected to liquid splash. A well documented subcircuit 43063 is given here. On a practical note, take extra care with board layout. To get a basic simulation going try the following commands.

It is also valuable for gaining an intuition into how circuits work. If the feedback voltage remains above 1. The upward slope of the switch current is due to the ramping up of the inductor current. The conversion to PSpice mentioned in reference 3 uses different syntax again. The aim of these notes is to provide some insight into the operation of the chip and associated circuits.

The RC integrators in the flip flop are also needed for the same reason. It is useful 344063 applications such as providing analogue positive and negative supplies from a single 5V logic supply in small circuit boards.

This is thought to be very effective, giving excellent transient performance, but its dx is not well understood.

Ignore any error messages about unrecognized parameters in the diode model. No abstract text available Text:
