PY-I-QUADTO39(7+1) (Rev. 4.0) Miniature Thin Film Four Channel Pyroelectric Sensor Introduction Unlike other pyroelectric materials, the Pyreos thin film pyroelectric sensors can be reduced in physical size and still provide high sensitivity with fast frequency operation, enabling this highly stable four element sensor in a TO39 package. This current mode sensor offers performance in a small footprint and up to 100 Hz data monitoring. The sensor has internal CMOS trans impedance amplifiers, with 10 G feedback resistors outputting voltage signals centred around half the supply rail. A range of IR filters are available.
