Security Sensors - Using RedRock® TMR Magnetic Sensors in Security Applications

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.

Proximity Sensing with RedRock® TMR Magnetic Sensors

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.

Device "Wake-Up" Sensors - using RedRock® TMR Magnetic Sensors

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.

Overview - Gen 2.0 TMR Demo Board (Tony Parakka)

Coto Technology Applications Engineer, Tony Parakka, provides a peek at Coto's newest 2.0 Generation demo board featuring RedRock TMR magnetic sensor products: RR111 (Analog Output); RR120 (Digital Unipolar Sensor); RR121 (Bipolar Digital Latching) and RR121 (Digital Omnipolar ). This video serves as a basic overview of the different products. Engineers can opt to see more in-depth, functional discussions on each individual product in Coto's new 4-video series of Engineering Discussions.
