PRODUCT DATA SHEET Two channel premium pyroelectric detector with high signal-noise-ratio PRODUCT DATA SHEET › Pyroelectric IR detectors › MPS2SENS | © Micro-Hybrid-Electronic GmbH | 2022-06 | All rights reserved. Higher precision and signal-noise-ratio Less sensitive to external interference due to internal signal amplification Less influence of temperature fluctuations due to low thermal mass High responsivity with modulation frequency up to 100 Hz Low microphone effect referring to low membrane mass Very low temperature dependence Amplified signal in current mode Short response time Broad spectral sensitivity 2 – 15 µm, optimized from 3 - 5 µm Higher read-out rate up to 100 Hz 2 chips with MEMS based CPM membrane High end solution for demanding applications Additional product information The absorption of the incident infrared radiation forms a temperature gradient across the detector membrane. Due to the pyroelectric properties of the sensor material, this temperature change is converted into a charge change which can be measured at the electrodes of the sensor chip. Micro-Hybrid’s CPM (ceramic pyroelectrical material) pyroelectric detectors use sensitive elements based on MEMS technology.

INFRARED COMPONENTS AND SYSTEMS The pyroelectric element consists of a approximately 0.5 µm thick thinfilm CPM mounted on a modified silicon-based membrane which is produced by a DRIE backetch process. The front electrode is optically transparent allowing infrared radiation to be absorbed by the active area. This area has a broad absorption range from 2 – 15

PRODUCT DATA SHEET › PYROELECTRIC IR DETECTORS › MPS2SENS Product overview RoHS compliance Our infrared detectors on pyroelectric basis, MPS series, are based on one or more MEMS sensor chips in a hermetic packaging, which in addition to a silicon carrier contain the piezoceramic PZT (lead zirconium titanate) as a functional thin film in small quantities. The substance compound PZT is excluded from the restriction according to Annex III (7c. I). Furthermore, our pyroelectric-based infrared detectors are exempt from RoHS Directive 2011/65/EU Article 4 (1) according to Annex IV (1c) when used...
