Which EMC (electromagnetic compatibility) devices are helpful for the design and rectification of syringe pumps?

Precision EMC design for syringe pumps requires attention to detail. The DC-DC module powering the stepper motor driver should have π-type filters added to both its input and output terminals. Ferrite bead sleeves can be fitted over the motor phase wires before they enter the lead screw mechanism. Sensors used to detect syringe plunger position or pressure (e.g., strain gauges) have very weak bridge output signals; therefore, instrumentation amplifiers should be used, and their power supply and input should be rigorously filtered and shielded. The inside of the entire pump's plastic casing can be coated with conductive paint and properly grounded to provide auxiliary shielding. For battery-powered syringe pumps, the battery connector contacts must be ESD protected.
