High Resolution, High Stability,Space-Saving and Cost-Saving
A&D’s AD-4212D series meets today’s increasing demand from the high-techindustry for in-line precision weighing by achieving a 1 μg readability to a capacityof 32 g and a 10 μg readability to a capacity of 320 g with short stabilization time,
while keeping both the cost and the space required for installation to a minimum.

Minimum weighing value from 1 μg
The AD-4212D enables the most minute weight measurement
and control for processes such as dispensing.

Direct connection to a PC or PLC
The AD-4212D is a weighing sensor with an integrated
analog-to-digital converter. It can output weighing results asdigital data directly to a PC or PLC*1, which saves space when you
do not need or have room for installing a separate display unit.

*1 A separately sold RS-232C cable for PC/PLC is required

Sensitivity adjustment using an internal weightThis function allows you to adjust the sensitivity of the AD-4212D to ensure its accuracy
quickly, easily, and correctly.

Guarded against vertical and transverse overloading
A&D’s patented shock absorber*2 under the weighing pan copes with movement in all
directions so that the sensor is protected from actuator malfunction.

Adaptable to a special weighing pan*2 Not designed to handle impact loads

You can design and attach your preferred weighing pan (or receptacle) when the standard
pan is unﬁt for your speciﬁc application.

Removable leveling feet
The AD-4212D can be secured directly to a base by removing the leveling feet and using screws.

High extensibility with various
external devicesWinCT-AD4212D (freeware)*3
Running on your PC, WinCT-AD4212D can display weighing values
in real time and be used to control the operation and change theinternal settings of the AD-4212D.

In addition to displaying weight values, performing re-zero, sensitivity adjustment, etc., theAD-8922A can output BCD, comparator or analog data by choosing the appropriate accessory.
The AD-8923-BCD and AD-8923-CC can transmit the weighing data through BCD and CC-Link
respectively.*4AD-8526 RS-232C/Ethernet (TCP/IP) converter (sold separately)
Via the AD-8526, the RS-232C output from the AD-4212D can be converted
and connected to LAN.
AD-8923-BCD/CC only displays the last six digits*4 The(but outputs the complete data).
