Mikroelektronika MIKROE-2985 AH1389 Ultra-Sensitive Unipolar Hall Effect Switch

Technical description of the product (MIKROE-2985):

The Mikroelektronika MIKROE-2985 Hall Switch click is a magnetic field activated dual-relay Click board™. It has two high-quality relays, which are activated by the Hall-effect sensor: when the north pole magnetic field is introduced to the sensor, one of the relays will be activated; when the south pole magnetic field is introduced to the sensor, the other relay will be activated. Two high-quality compact relays allow switching of high voltages – up to 220V, so they can cut or establish a connection on the main side of the circuit. It can be used for applications activated by the magnetic field, such as contactless switches, door, lids or tray position detecting switches, or other similar applications that require contactless switching of the relay contacts. Key features include reliable contactless switching by the magnetic field, separate sensors for both south and north pole magnetic fields, and high-quality compact OMRON relays. It uses a GPIO interface and supports 3.3V or 5V input voltage. The click board size is L (57.15 x 25.4 mm).
