This is a macro shot of a passive infrared sensor in a motion detector. I took this for a display in a product show that I'm participating in.
THP00C0000
The THP motor protection module has been especially designed for scroll compressors.
According to the DIN 44081/082 standards, up to 9 PTC temperature sensors, with different rated response temperatures, can be connected in series to the input of the measurement circuit.
"Rated temperature" refers to the temperature above which the resistance of the PTC increases very quickly.
As soon as the temperature in one of the monitored areas exceeds the rated response temperature of the corresponding PTC sensor, the THP motor protector module is activated, and consequently de-energises the relay.
When the protector is activated a timer is started; the protection mechanism can only be disabled 30 minutes after activation, and when the PTC signals (the resistance of the sensors) have fallen below the reset threshold.
Key Takeaway: The Ultrasonic sensor sends out an ultrasonic signal. When this signal hits an object, it bounces back like an echo, and the time between the ping and the echo is used to calculate distance.

My 400D is a bit over a year old now with around 25000 actuations (bought new). Never cleaned the sensor. Attempted to clean it today but was not very successful. Need better tools I think.
