TECHNICAL & COMMERCIAL FAQS

SL20 Buyer & Engineering FAQs

Is the M3 Mobile SL20 tough enough for warehouse floor use?

Yes, it carries IP67 dust/water sealing and survives 1.8 m drops to concrete inside its rugged protective boot, making it ideal for light to medium warehousing, picking, and field work.

Should we choose the 3,000 mAh standard or 5,000 mAh extended battery?

The 3,000 mAh battery easily covers a standard 8 hour barcode shift at minimal weight (236 g); specify the 5,000 mAh extended pack for 12 hour shifts or heavy 4G GPS usage.

Can we add a pistol trigger handle to the SL20?

Yes, snap on barcode pistol handles and M3 UHF RFID sleds connect cleanly via integrated pogo pins.
