I have tried this combination Pin 1 : 5v Pin 2 : Ground Pin 3 : out put. In output i am observing voltage same as pin 1 (Power), if i change decrese the power propotionally out put also decreses. And current consumed was 1mA. I am also attaching a image of internal pcb structure of oil level

But i dont have the information of pin details. i tried with different combination. but at one iteration sensor got spoiled. (observed smoke). now i have new sensor. so i want to make sure the pin details first

Hello, I am testing a engine oil level sensor. in this i dont know the type of the sensor. and pin descripion. I initially thought the sensor type was analog. Since i dont know the proper pin information i cant confirm it. Can some of you explain how this sensor works, how to test it. Sensor...

For wiring I have used twisted shielded pair cables. When I am adding a common mode choke I am able to see reduction in emissions. Are there any other methods which I can try?

Can you please provide details on how can I check if it is common mode or difference mode emission? I am new to this topic and still learning. It would be really helpful.

This is a new board in which I am trying to solve the above mentioned problem. I am having one set of unit only. Will check this.

If the active board fails, then it automatically switches to another board and I need it to work identically. No only the active board will be connected to load, but if the active board fails then it switches to another board. Until I restart the unit, it doesnt come back to the expected voltage.

The unit consumes max 3A at 28VDC supply. Would you suggest any ferrite bead value?

Yes I have another main PCB that consists of relays to select which one of these PCBs must be active. Injectors are capacitive load.

There are signals given as input to actuators along with 28V supply. It is failing at all frequencies from 10kHz to 10MHz.

I'm seeking assistance and recommendations for CE-102 testing (MIL-STD 461). When I power on my unit, the emission levels significantly exceed the limit. Since the unit is already designed, I cannot make any internal modifications. Could you please suggest potential causes for this issue and...

In my project, I have two PCBs, each containing a fuel injector actuation circuit powered by a HRL3024S200P converter. Both PCBs include four injector circuits, which operate continuously. However, the injectors (4) are connected to only one of the boards at any given time, based on a selection...

PWM is given from a function generator.

Is there any method by which i can determine the rated voltage of a solenoid coil by using the coil resistance?

In my application I require the pump to open at less duty cycle. While testing I observed that when the supply voltage was increased to 24V the pump actuated at lesser duty cycle.
