Coto Technology, a leading manufacturer of reed relay switches and TMR-based sensors, has recently introduced a new analog sensor. The new RedRock RR110 wafer-based TMR (Tunneling Magnetoresistive) unit is offered in small package size yet offering strong magnetic sensitivity and high directionality and that too at a highly competitive price.

 

The new sensor is ideally suitable for continuous fluid measurement applications such as countertop appliances, utility meters, white goods, security and anti-tampering applications, medical devices, industrial positioning, and other proximity sensing applications. Developed with minimal design efforts, the RR110 can serve as an easy replacement to a complex, costly and vulnerable bare glass reed switch ladder like those found in fluid level sensing applications with a single sensing element. 

 

 

 

Moving on, it has a highly linear response which renders reliable functionality with a wide range of magnets across wide activation distances. It also features high resistance to shock and vibration. Besides, it comes with the industry standard SOT-23 ruggedized package that easily handles tough environments and ensures maximum manufacturability for automated pick and place operations. 

 

 

The RedRock RR110-A111-00 TMR analog sensor can be availed at the unit price of $2.95 (with high volume application pricing below $0.50). It’s also available with an evaluation kit containing a motherboard mounted with both RR110 and RR130 at opposite ends, a magnet, other accessories along with full documentation.
