Mounting Instructions
Use two 3,0 x 0,5 mm thread machine screws to attach to the
bottom or rear 23203B mount faces. Be careful not to bottom
screws in tapped holes as this can strip threads. Alternatively, the
two thru holes allow two #6 or two 3,5 mm screws to be used to
mount the 23203B from the top.
➤ A light film of oil or silicone grease can be used to enhance
contact between mounting surfaces.
➤ A locking compound should be used on all threads to prevent
screws loosening due to vibrations.

How to Use the 23203B
Connect a +8 to +30V DC power source to pins 8 and 9.
Connect a differential or floating input A/D converter to each
signal and signal common pins (pins 5 and 6 for Accelerometer 1,
pins 1 and 2 for Accelerometer 2, and pins 3 and 2 for
Temperature). For best results use a converter with an input
impedance greater than 1MΩ and common mode rejection ratio
greater than 60dB. Single-ended converters are not
recommended but if used, leave Signal Common unconnected to
eliminate ground loops. A positive acceleration (labeled on the
accelerometer cover) causes a positive change on the
corresponding output.
➤ Keep cable lengths between the accelerometer and A/D converter
as short as practical. Use shielded twisted pair wiring, especially
near electric motors or other noise sources.
➤ As a rule of thumb, sample frequency should be at least 10 times
the signal bandwidth when linear interpolation is used for signal
reconstruction. Built-in or external low-pass filtering can be used
to lower the noise floor and eliminate spurious peak
measurements from short-duration shock impulses with
insignificant energy content.
➤ A logic 1 on the self-test input will add 0.1 to 0.5V* to both
accelerometer outputs. An output that changes less than +0.1V*
or more than +0.5V* indicates a defective channel, shorted pin,
or broken wire. The self-test signal is approximate and should not
be used for calibration. If the self-test feature will not be used, pin
7 should be connected to pin 9.
