Isotron® accelerometer 4 PIN RECEPTACLE MATES WITH CABLE ASSEMBLIES Y-AXIS OUTPUT UNIT IDENTIFICATION STANDARD TOLERANCE INCHES [MILLIMETERS] • General purpose triaxial Isotron® accelerometer • Wide frequency bandwidth • Hermetically sealed • Small 14mm cube size • IEEE P1451.4 TEDS capable Model 44A is a cost effective general purpose triaxial Isotron accelerometer designed for use in a variety of applications. 44A is a 14 mm cube shaped Isotron accelerometer, featuring a single threaded V<i-28 4 pin connector. The unit is hermetically sealed against environmental contamination. Model 44A features an annular shear ceramic crystal which exhibits excellent output stability over time. The accelerometer incorporates an internal hybrid circuit with TEDS in a two-wire IEPE system which transmits its low impedance voltage output through the same cable that supplies the constant current power. Signal ground is connected to the outer case of the unit. Isolated mounting studs are available. Polarity inversion protection for the hybrid circuit is inherent in the circuit design. 44A is available in four sensitivities designated by a two digit suffix. The 44A13 has a sensitivity of 10 mV/g, the 44A14, 44A15 and 44A16 have sensitivities of 25 mV/g, 50 mV/g and 100 mV/g respectively. The customer may select the mounting stud size included standard with the unit. The available stud sizes are 10-32, 1/4-28, M5 and M6. The stud size is designated following a dash after the model This product is fully compliant to the European Union's Low Voltage Directive, 2006/95/EC and EMC Directive 2004/108/EC and is eligible to bear the CE Mark.
