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 FEATURES thickness of the element. Thin Piezo polymer w/ high piezo activity The DT series sensors are the simplest form of piezo Flexible silver ink metallization film sensors, used primarily as dynamic strain gages and Min. input impedance: 1 M, contact microphones for vibration or impact detection. recommended: 10 M These are available without any leads for those 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 9/2015 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., Measurement Specialties Measurement Specialties (China), Ltd., a TE Connectivity Company (Europe), Ltd. a TE Connectivity Company 1000 Lucas Way a TE Connectivity Company No. 26 Langshan Road Hampton, VA 23666 26 Rue des Dames Shenzhen High-Tech Park (North) Sales and Customer Service 78340 Les Clayes-sous-Bois, France Nanshan District, Shenzhen, Guangdong P Tel: +1-800-745-8008 or Tel: +33 (0) 130 79 33 00 rovince, China 518107 +1-757-766-1500 Fax: +33 (0) 134 81 03 59 China Fax: +1-757-766-4297 Sales: pfg.cs.emea meas-spec.com Tel: +86 755 3330 5068 Technical Support Fax: +86 755 3330 5099 Email: piezo meas-spec.com Sales: pfg.cs.asia meas-spec.com TE.com/sensorsolutions Measurement Specialties, Inc., a TE Connectivity company.
