It includes a dual element pyroelectric ceramic with FET in source follower connection and RF protection by a resistor and additional capacitor. This detector is available in TO-5 housing with an infrared filter which protects the elements from strong white light disturbance. It offers high responsivity with excellent common mode performance (match) and low noise.
