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 Flexible silver ink metallization Min. input impedance: 1 MΩ, recommended: 10 MΩ Output voltage- mV to 100s of volts Operating temp: -40 to 60°C APPLICATIONS     The DT series sensors are the simplest form of piezo film sensors, used primarily as dynamic strain gages and contact microphones for vibration or impact detection. These are available without any leads for those applications where the customer wants to make their own lead attachment. The sensor can be readily adhered to a surface with double-sided tape or epoxy. Lead attachment can be achieved by compressive clamping, crimps, 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) Model Number Part Number Film Thickness A Film B Electrode C Film D Electrode Total Thickness (μm) Cap (nF) DT1-028K 1-1002608-0 28 μm .64 (16) .484 (12) 1.63 (41) 1.19 (30) 40 1.38 DT1-052K 2-1002608-0 52 μm .64 (16) .484 (12) 1.63 (41) 1.19 (30) 64 .740 DT2-028K 1-1002145-0 28 μm .64 (16) .484 (12) 2.86 (73) 2.42 (62) 40 2.78 DT2-052K 2-1002145-0 52 μm .64 (16) .484 (12) 2.86 (73) 2.42 (62) 64 1.44 1-1002149-0 28 μm .86 (22) .740 (19) 6.72 (171) 6.13 (156) 40 11.00 2-1002149-0 52 μm .86 (22) .740 (19) 6.72 (171) 6.13 (156) 64 5.70 DT4-028K DT4-052K NORTH AMERICA EUROPE ASIA Measurement Specialties, Inc., a TE Connectivity Company 1000 Lucas Way Hampton, VA 23666 Sales and Customer Service Tel: +1-800-745-8008 or +1-757-766-1500 Fax: +1-757-766-4297 Technical Support Email: piezo@meas-spec.com Measurement Specialties (Europe), Ltd. a TE Connectivity Company 26 Rue des Dames 78340 Les Clayes-sous-Bois, France Tel: +33 (0) 130 79 33 00 Fax: +33 (0) 134 81 03 59 Sales: pfg.cs.emea@meas-spec.com Measurement Specialties (China), Ltd., a TE Connectivity Company No. 26 Langshan Road Shenzhen High-Tech Park (North) Nanshan District, Shenzhen, Guangdong P rovince, China 518107 China Tel: +86 755 3330 5068 Fax: +86 755 3330 5099 Sales: pfg.cs.asia@meas-spec.com TE.com/sensorsolutions Measurement Specialties, Inc., a TE Connectivity company.
