Interface Misc, LDT Series Elements With Lead Attachment And Lamination

LDT Series Elements

with Lead Attachment and Lamination

The 'l' In Ldt Stands For 'laminated' Sensor. Typically, A 0.005" (125 M) Polyester Layer Is

Laminated To A 28 M Or 52 M Piezo Film Element. When Used In A 'bending' Mode, Laminated Film

Elements Develop Much Higher Voltage Output When Flexed Than A Non-laminated Dt Elements Series. The

Neutral Axis Is In The Laminate Instead Of In The Film So The Film Is Strained More When Flexed.

The Capacitance Is Proportional To The Area And Inversely Proportional To The Thickness Of The

element.

Piezo Film Sensors Ldt Elements Are Available In A Variety Of Lead Attachment Options. For

Significantly Increased Sensitivity, The Ldtm-028k (m-mass) Combines An Ldt0-028k Form Factor With

The Addition Of A .72 Gram Round Mass. The Ldt1, 2 And 4 Have 12" Of 26 Gauge Twisted Pair Wire.

The Ldt0-028k And Ldtm-028k With Solder Tabs Can Be Soldered Directly To A Pcb With A Reasonable

Level Of Care. Piezo Film Cannot Withstand High Temperatures (>80 C), And Therefore Soldering Of

The Pins To A Pcb Must Be Done Quickly. A Heatsink Clamped To The Interface Area Between The Film

And The Crimps Will Take The Heat Away From The Film. Pre-tin The Pcb And Then Quickly Solder The

Sensor To The Board. Do Not Allow The Soldering Iron To Touch The Film, And Do Not Use A Dwell Time

of over 5 seconds on the pins. Low temperature solders can also be used.

switches for counters and momentary closure type switches.

For Tightly Tolerance Sensitivity Requirements, Please Consult Msi Sensors For Techniques Used To

control variations of boundary conditions in production.

Applications For This Include Beam-type Vibration Sensors For Vehicle Alarms And Solid State
