Magnetic Reed Switch Sensor Module
Features
- Reed sensor module, is a kind of passive electronic switch . with a simple structure, small size , and easy to control.
- It consists of a sealed glass tube with two elastic spring plates of iron, also called rhodium metal and filled with inert gas.
- Normally, the two reed glass tube made of special materials are separated. when a magnetic substance nears the glass tube, under the action of the magnetic field lines ,the two reed tubes are magnetized to attract each other and the contact spring will pull together to make a circuit node.
- If the external magnetic is removed, the two reeds are separated and the line is disconnected.
- Therefore, as a signal to control the use of a magnetic field line switching devices, reed can be used as a sensor for counting, limit, etc. (in the security system is mainly used for door sensor, magnetic window production), but also is widely used in a variety of communications devices.
- 1 Reed needs and with the use of magnets in magnetic induction for a certain time, will form a conduction state, the module output low, when there is no magnetic force, it is in disconnected state, the output high, reed and sensing distance beyond the magnet - working distance: 1.5 cm

Would not work in my jeep
Color: Textured
This seems like a decent holder, however it is not universal as it would not fit in my jeep. Check to make sure you have the right kind of air vents for it. I could not get it to work for my vehicle as the vents are too wide.

Works great!
Color: Black, Color: Black
This is a very simple, lightweight phone mount. It works well, I’m surprised how securely it fits on the car vent. I’ve tried others and couldn’t get them to fit right. My phone slides into the top and fits nicely. It was easy to install.

Nice, and would buy it again
Style: Qi2 Charging Mount
So far I'm liking this product. For the model X, you can use it on either side of the screen. As well, it holds on very well on the screen. Very good build quality and design. Fits perfectly to the screen. Very strong magnetic fit. But can cause scratches to your case if tth case is a hard plastic material.

Not perfect, but good enough for daily use
Style: Qi2 Charging Mount
Well made and very strong magnet. Make sure you tighten it completely or it will fall off. The tightening screws are not intuitive, but after some confusion you can figure it out. Works as intended and charging is as fast as your phone allows.
