REED Click
R160.00 ex. VAT
REED Click is a compact add-on board that adds an electromagnetic switch to your application to control the flow of electricity in a circuit. This board features CT10-1540-G1, a Coto Classic C10 series molded reed switch from Coto Technology. This sensor uses a presence of a magnetic field to make contact with internal poles, thus enabling the flow of electricity through itself in a circuit. The two contacts are separate until a magnetic field is applied, which snaps them, activating the switch. This Click board™ makes the perfect solution for proximity sensing, security alarm sensor, level sensor, flow sensor, pulse counters, and more.
REED Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

How does it work?
REED Click is based on the CT10-1540-G1, a Coto Classic C10 series molded reed switch from Coto Technology. This hermetically sealed low-current dry reed switch is an SPST type (single pole, single throw), having normally-open ruthenium contacts. The sensor is a double-ended type and may be actuated with an electromagnet, a permanent magnet, or a combination of both. The CT10-1540-G1 designation indicates that this sensor has a sensitivity range from 15 to 40AT and a release range from 3 to 39AT. The sensor has resistance to vibration of 10G and resistance to a shock of 100G, which ensures that the switch will not be activated with anything, but the electromagnetic field.
The REED Click uses a single CS pin of the mikroBUS™ socket connected to the host MCU to output 1 or 0, depending on whether the switch is closed or open. The sensor has two separate pole contacts inside a glass casing (north and south). When a magnetic field is applied, it snaps them shut, thus activating the switch. Once the magnet is removed, they open up again. The sensor is activated by a magnetic field and not the distance of that field to the sensor. A stronger but farther field counts more than a weaker but closer one. In addition, this Click board™ features an L1 LED to present the activated switch visually.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the PWR SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
