Rd-624 pyroelectric infrared sensor
Product catalog Download
product details
Pyroelectric infrared sensor uses the characteristics of temperature change to detect infrared radiation, and uses the complementary method of two sensitive elements to suppress the interference caused by temperature change, which improves the working stability of the sensor. Products are widely used, such as safety device, anti-theft alarm, induction door, automatic lamps, intelligent toys, etc.
Sensor features
High sensitivity and superior SNR;
The dual compensation structure is adopted to effectively resist the external environment interference;
The components and amplifiers are packaged in TO-5, which saves the time of circuit design and mounting;
Excellent anti-interference. Because the whole circuit is packaged in metal package, the electromagnetic shielding effect is better;
The interference filter has high cut-off depth and strong white light resistance;
Main applications
Intelligent office appliances
Home, smart home;
Automatic lighting switch, safety door;
Security, intrusion alarm, indoor access management;
