DT SENSORS SPECIFICATIONS Piezoelectric film sensor without lead attachments Silver ink electrode Available in different sizes and thicknesses Great for making your own sensor The DT series of piezo film sensors elements are rectangular elements of piezo film with silver ink screen printed electrodes. They are available in a variety of different sizes and thicknesses. The DT film element produces more than 10 millivolts per microstrain, about 60 dB higher than the voltage output of a foil strain gauge. The capacitance is proportional to the area and inversely proportional to the thickness of the element. FEATURES Thin Piezo polymer w/ high piezo activity The DT series sensors are the simplest form of piezo film sensors, used primarily as dynamic strain gages and Flexible silver ink metallization contact microphones for vibration or impact detection. Min. input impedance: 1 M, These are available without any leads for those recommended: 10 M applications where the customer wants to make their own Output voltage- mV to 100s of volts lead attachment. The sensor can be readily adhered to a Operating temp: -40 to 60C surface with double-sided tape or epoxy. Lead attachment can be achieved by compressive clamping, crimps, APPLICATIONS eyelets, conductive epoxy or low temperature solders Sensing contact forces Recording the time of an event Counting the number of impacts Make your own sensor element SENSOR SOLUTIONS /// DT 07/2017 Page 1 DT SENSORS DIMENSIONS and PART NUMBERS Dimensions in inches (mm) Total Film A B C D Cap Model Number Part Number Thickness Thickness Film Electrode Film Electrode (nF) ( m ) 28 m .64 (16) .484 (12) 1.63 (41) 1.19 (30) 40 1.38 DT1-028K 1-1002608-0 52 m DT1-052K 2-1002608-0 .64 (16) .484 (12) 1.63 (41) 1.19 (30) 64 .740 28 m DT2-028K 1-1002145-0 .64 (16) .484 (12) 2.86 (73) 2.42 (62) 40 2.78 DT2-052K 2-1002145-0 52 m .64 (16) .484 (12) 2.86 (73) 2.42 (62) 64 1.44 28 m DT4-028K 1-1002149-0 .86 (22) .740 (19) 6.72 (171) 6.13 (156) 40 11.00 52 m .86 (22) .740 (19) 6.72 (171) 6.13 (156) 64 5.70 DT4-052K 2-1002149-0 NORTH AMERICA EUROPE ASIA Measurement Specialties, Inc., MEAS Deutschland GmbH Measurement Specialties (China), Ltd., a TE Connectivity Company a TE Connectivity Company a TE Connectivity Company Tel: +1-800-522-6752 Tel: +49-800-440-5100 Tel: +86 0400-820-6015 Email: customercare.dtmd te.com Email: customercare.dtmd te.com Email: customercare.chdu te.com TE.com/sensorsolutions Measurement Specialties, Inc., a TE Connectivity company.
