GENTEC-EO thermoelectric sensor QS5-H

Product Name: GENTEC-EO thermoelectric sensor QS5-H

Product Model: QS5-H

Product Introduction Our pyroelectric detector belongs to the category of room temperature detectors, and when exposed to a radiation source, the current output generated is proportional to the rate of temperature change. Its working principle can be described through an AC current source, capacitors, and resistors. The current output follows the formulaI = p(T)·A·dT/dt， Where I is the current value, p (T) is the thermoelectric coefficient, A is the effective area defined by the front electrode, and dT/dt is the temperature change rate of the thermoelectric crystal. The advantages of pyroelectric detectors compared to other infrared detectors include room temperature operation, wide spectral response, high sensitivity (D *), and fast response (sub nanosecond response under 50 Ω load). QS5-H discrete thermoelectric sensor with metal coating, high average power. The TO5 and TO8 packaging make the QS-H detector compact and easy to integrate into existing systems. 5mm and 9mm diameter thermoelectric sensors simplify optical alignment operations.
