They are available in a variety of different sizes and thicknesses. Lead attachment is accomplished using a riveted lug going to 12” (300 mm) of 28 AWG wire. The DT film element produces more than 10 millivolts per micro-strain. The capacitance is proportional to the area and inversely proportional to the thickness of the element. The DT elements are supplied with a thin protective coating over the active electrode area to prevent oxidation to the top surface of the silver ink. 216 kt V0 Piezoelectric film sensor AC Coupled Silver Ink Electrodes Protective Coating over Electrodes Lead Wires Attached with Rivets. 14% SENSOR SOLUTIONS /// DT Series Rev 1 FEATURES      Minimum Impedance: 1 MΩ Preferred Impedance: 10 MΩ and higher Output Voltage: 10 mV to 100V depending on Force and Circuit Impedance Storage Temperature: -40°C to +70°C [-40°F to 60°F] Operating Temperature: 0°C to +70°C[32°F to 160°F] APPLICATIONS     Sensing Direct Contact Force Recording Time of an Event Counting Number of Impact Events Measuring Impact Related Events 9/2015 Page 1 DT SERIES ELEMENTS WITH LEAD ATTACHMENT 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/L w/rivets 1-1002908-0 28 μm .64 (16) .484 (12) 1.63 (41) 1.19 (30) 40 1.38 DT1-052K/L w/rivets 2-1002908-0 52 μm .64 (16) .484 (12) 1.63 (41) 1.19 (30) 64 .740 DT2-028K/L w/rivets 1-1003744-0 28 μm .64 (16) .484 (12) 2.86 (73) 2.42 (62) 40 2.78 DT2-052K/L w/rivets 2-1003744-0 52 μm .64 (16) .484 (12) 2.86 (73) 2.42 (62) 64 1.44 DT4-028K/L w/rivets 1-1002150-0 28 μm .86 (22) .740 (19) 6.72 (171) 6.72 (171) 40 11.00 DT4-052K/L w/rivets 2-1002150-0 52 μm .86 (22) .740 (19) 6.72 (171) 6.72 (171) 64 5.70 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 MEAS Deutschland GmbH a TE Connectivity Company Hauert 13 44227 Dortmund Germany Sales and Customer Service Tel: +49 (0)231 9740 21 Technical Support Tel: +49 (0)6074 862822 Email: piezoeurope@meas-spec.com Measurement Specialties (China), Ltd., a TE Connectivity Company F1.6-4D, Tian An Development Compound ShenZhen, China 518048 Sales and Customer Service Tel: +86 755 8330 1004 Technical Support Email: piezo@meas-spec.com TE.com/sensorsolutions Measurement Specialties, Inc., a TE Connectivity company.
