Small Batch Coding
RNJet T1
Compact batch coder for precise date and lot codes on smaller parts and packaging.
View Full SpecsCoding & Marking on Electronics
Non-contact, precise marking for PCBs, enclosures, cables and connectors, plus high-speed coding for retail packaging.
Electronics Manufacturing
Precise, non-contact marking for delicate components
Electronics manufacturers mark PCBs, enclosures, cables, connectors and retail packaging with date codes, lot numbers and serial numbers — often on small, delicate or static-sensitive parts where contact printing risks damage.
RNJet piezo printers mark without touching the part, from up to 15 mm away, while RNJet thermal inkjet printers handle high-speed date and lot codes on retail and bulk packaging — without the daily cleaning and makeup fluid continuous inkjet (CIJ) printers require.

FAQ
Electronics Coding & Marking FAQ
PCBs and components, enclosures and housings, cables and connectors, and the retail and bulk packaging those products ship in.
Yes. RNJet piezo printers mark from up to 15 mm away, which avoids the contact risk that can damage delicate or static-sensitive parts.
Yes. RNJet printers support auto-incrementing serial numbers, date codes, lot numbers and GS1 DataMatrix for component-level traceability.
RNJet thermal inkjet and piezo printers avoid the daily cleaning, makeup fluid and nozzle maintenance that CIJ printers require, while printing comparable or higher-resolution codes.
Yes. RNJet printers mount directly on new or existing lines and trigger from a photo-eye or PLC signal without slowing the line.
