Part number

US1881

Operate temperature

K:-40~125℃

Package

TO-92UA/SOT23

 

General Description

The US1881 is a bipolar Hall effect sensor IC fabricated from mixed signal CMOS technology. It incorporates advanced chopper
stabilization techniques to provide accurate and stable magnetic switch points. There are many applications for this HED in addition to
those listed above. The design, specifications and performance have been optimized for commutation applications in 5V and 12V brushless DC motors.

The output transistor will be latched on (BOP) in the presence of a sufficiently strong South pole magnetic field facing the marked side of the package.
Similarly, the output will be latched off (BRP) in the presence of a North field. The SOT-23 device is reversed from the UA package.

The SOT-23 output transistor will be latched on in the presence of a sufficiently strong North pole magnetic field applied to the marked face.

Original imported flexiforce film pressure sensor A301 1/25/100lbs

The A301 is optimized for high volume manufacturing and ideal for embedding into products and applications. The sensors are available in three force ranges: Low 4.4 N (0 - 1 lb), Medium 111 N (0 - 25 lb) and High 445 N (0 - 100 lb). The force ranges stated are approximations. The dynamic range of this small force sensor can be modified by changing the drive voltage and adjusting the resistance of the feedback resistor.

Thin film pressure sensor, Square 16 nodes side length 20 mm flexible resistive motion sensor

The IMM0092 of Idong Film Electronics is a member of the single-node sensor family. Although IMM092 has 16 nodes, because IMM00092 has 32 lines of output, each node has 2 lines of output, and the 16 nodes are independent of each other. They are very reliable piezoresistive sensors. When the pressure (pressure) applied to the effective area of the sensor increases, the output resistance of the sensor decreases. Single-point sensors can be measured using a multimeter or customer's own circuit.

Force Sensor RP-C18.3-ST Flexible Thin Film Pressure Sensor Intelligent 20g-6kg

The flexible sensor has the characteristics of flexible ultra-thin, ultra-low power consumption and extreme speed response, etc. Small size, this flexible pressure sensor is based on new nanometer pressure-sensitive materials ​supplemented by ultra-thin film substrate. This pressure sensor has the characteristic of high stability, high consistency. Highly sensitive flexible nanometer materials can realize highly sensitive detection of pressure.

Smart Electronics Hydrogen sulfide sensor probe MQ-136 Toxic gas H2S sensor MQ136

Hydrogen sulfide sensor probe MQ-136 Toxic gas H2S sensor MQ136 The gas-sensitive material used in the MQ136 hydrogen sulfide gas sensor is tin dioxide (SnO2) with low conductivity in clean air. When there is hydrogen sulfide gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of hydrogen sulfide gas in the air increases. Using a simple circuit, the change in conductivity can be converted into an output signal corresponding to the gas concentration.

FSR406 Pressure Sensor , 100% New and Original Force Sensitive Resistor

This is a force sensitive resistor with a square, 1.75x1.5", sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg.
