Coto device simulation and validation services for TMR magnetic sensor integration Through use of specialised design simulation and validation development services, Coto Technology helps customers to accelerate the effective design & development of magnetically-actuated devices which feature the use of Coto’s TMR magnetic sensors. |

Proximity sensing with RedRock® TMR magnetic sensors video RedRock® TMR magnetic sensors can be used in a wide variety of proximity applications such as detecting the opening/closure of an automatic sliding gate or detecting position of a linear actuator or a conveyor belt. This brief video demonstrates an example using feedback from a TMR sensor to stop a moving motor. Requirements met by the TMR sensors are high reliability, extremely low current drain (which is important if the device is battery powered) and a high level of sensitivity. |

Security sensors - Using RedRock® TMR magnetic sensors in security applications video Security applications use magnetic sensing in their devices to detect the unauthorized opening of a door or window. The main mechanism typically consists of a digital magnetic sensor and a magnet that are close to each other when the door/window is closed. In the event of an intrusion, the magnet moves away from the sensor, an action which is designed to trigger an alarm. While the application is fairly simple, the requirements of the sensor are significant. Featuring RedRock® TMR magnetic sensors’ extremely low power consumption, high sensitivity, ultra-miniature size and high degree of robustness and reliability, this brief video demonstrates TMR to be the ideal solution when used in security devices. |
 |
Device "Wake-Up" Sensors - using RedRock® TMR Magnetic Sensors video To conserve battery power, many devices are kept “asleep” or turned off until the time is right for them to operate. When the device is removed from its enclosure, a sensor is used to trigger its “wake-up.” In this brief video, this function is explained and demonstrated using a RedRock® TMR magnetic sensor within a medical pill camera device which requires the sensor to be tiny, highly sensitive and able to operate within a hermetically-sealed environment while using nearly zero power. |
