Vibration Sensor Shock Sensor

This is a handmade vibration sensor (shock sensor).
It was very popular among my fellow association members, so I decided to offer it.
Here are the pros and cons of this product:
During linkage tests with VCB, the sensitivity is too high and it detects slightly too early (sometimes reacting to the click of the coil).
While within the acceptable range numerically, please refrain from purchasing if you require extremely high precision.
During linkage tests with SOG, you can achieve linkage simply by attaching this product to a utility pole with the magnet.
This resolves the hassle of needing to jumper a PAS, which is normally required when power is lost during completion inspections.
As this is a handmade item, please refrain from purchasing if you are looking for perfection.
Each unit is tested individually with a testing machine after creation.
We will test it again before shipping.
I believe this product is helpful for anyone involved in electrical work or testing, no matter how many they have (*^^*)
Neodymium magnets are used.
Please refer to the 4th image for color patterns (all black is also available).
Feel free to ask any questions!
