A&D Weighing AD-4212D-33S Weigh Module, 32 g x 0.001 mg

The A&D AD-4212D-33S is designed for ultra-precise weighing in automated production lines, research systems, draft chambers, glove boxes, and other equipment where a conventional standalone balance may not be practical. Its 32 g capacity and 0.001 mg (1 µg) readability make it especially useful for very small samples, dispensing, dosing, filling, and high-precision quality-control processes.

Yes. Automation is one of the primary purposes of the AD-4212D-33S. It provides direct digital weighing-data output and can communicate with a PC or PLC through RS-232C. With compatible A&D accessories, additional interfaces such as RS-485, Modbus RTU, EtherNet/IP, BCD, comparator, analog, and CC-Link can also be supported, giving system designers considerable integration flexibility.

Yes. The AD-4212D-33S incorporates an internal calibration weight, allowing sensitivity adjustment without relying solely on an external calibration mass. This is particularly valuable when the weighing module is installed inside automated machinery or an enclosed system where manually placing calibration weights on the pan would be inconvenient.

The AD-4212D-33S incorporates A&D's patented shock-absorbing mechanism beneath the weighing pan. It is designed to accommodate movement in multiple directions and help protect the precision weighing mechanism if an actuator or automated handling device accidentally contacts or overloads the pan. This makes the module particularly valuable for robotic and automated production applications.

The weighing module can achieve IP65-compliant dust and water protection when the supplied waterproof cleaning cap is installed in place of the weighing pan. This allows the unit to be better protected during cleaning. Because the IP65 condition depends on using the cleaning cap rather than the normal weighing pan, your product page should avoid implying that the module is fully IP65-protected during normal weighing operation.
