Coto's RedRock TMR is an integrated digital magnetic sensor ideal for use in medical, industrial, automotive, and consumer switching applications. Based on patented tunneling magnetoresistance (TMR) technology with CMOS process, the RedRock series can function even in low magnetic fields with large air gaps. The sensors are intended to replace bare glass reed switch applications where shock and vibration limit their applications. Applications include door, window, or lid closures; water and gas meters; fluid level detection; and many others. These tiny sensors offer high magnetic sensitivity with high hysteresis, EMF resistance, and a small package size, all while consuming very little power.
