HCZ-H8-B

Humidity Sensor Type HCZ-H8 Description This product specification is applied to the Humidity Sensor Type HCZ-H8. The terminal electrode material uses lead free solder (Sn / Ag / Cu). This product is conformity with RoHS directive which means that lead, cadmium, mercury, hexavelent chromium and specific bromine-based flame retardants have not been used. Applications The applications of the component are used in relative humidity measurement, control and display. There are many end products can be used. For example air conditioner, humidifier, dehumidifier, hygrometer, recorder, transmitter etc. Model Number HCZ - Product Type H8 Dip Type Humidity Sensor, H : ±3% RH - A With (A) / Without (B) Housing Package Each Pieces Configuration and Main Parts Configuration : (Units : mm) Symbol Dimensions (mm) A 8.3 ±0.2 B 13.5 ±0.2 C 4 ±0.5 D 15 ±2 E 2.54 ±0.2 F 0.5 ±0.1 G 0.2 ±0.1 H 2 ±0.5 I 5.08 ±0.3 J 10 ±0.3 www.element14.com www.farnell.com www.newark.com Page 04/06/11 V1.1 Humidity Sensor Type HCZ-H8 Main Parts No. Parts Reference 1 Sensor case PBT 2 Substrate Alumina 3 Sensing material Polymer 4 Electrode Ag / Carbon 5 Lead frame Phosphor bronze Electrical Characteristics General Characteristics: Units Min.
