Technical Buying Guide for UK Till Drawers

Selecting the correct cash drawer for a commercial EPOS system requires matching the physical dimensions of your counter space with the electrical requirements of your receipt printer. While standard drawers look similar from the outside, internal build components, roller mechanics, and firing voltages dictate how long the hardware will last under heavy operational use.

Understanding RJ11 Kick-Out Voltage: 12V vs 24V

The majority of automated till drawers are printer-driven. They do not plug into your tablet or terminal directly; instead, they connect via an RJ11/RJ12 cable (resembling a standard telephone wire) into the back of your thermal receipt printer. When a cash transaction is finalised, the printer sends an electrical pulse to trigger the drawer latch.

• 24V Systems (Standard): Industry-standard receipt printers from Star Micronics, Epson, and Bixolon operate on a 24V solenoid pulse. Connecting a 24V drawer to these units ensures reliable, instant opening.
• 12V Systems: Certain specialised touchscreen terminals, direct 12V POS matrix setups, or specific mobile printers deploy a lower 12V trigger pulse. Attempting to drive a 24V drawer with a 12V signal will result in a weak electronic pull, preventing the latch from releasing. Always verify your printer power supply output before choosing your hardware.
• USB & Manual Alternatives: If your business operates entirely without a physical receipt printer, you will require either a dedicated USB cash drawer (which uses a software virtual COM port driver to trigger the internal solenoid) or a manual mechanical drawer operated solely via a key-lock or front-push latch.

GBP Insert Layouts and Under-Counter Security

Our selection includes drawers designed with adjustable note dividers configured to securely hold British Pound Sterling (GBP) bank notes without folding. For quick shift handovers in high-turnover bars or clubs, look for models featuring fully removable internal coin trays or complete lockable spare inserts with transport lids. This allows cash counts to take place safely in the back office while a fresh till insert is loaded onto the shop floor.

If you are planning to mount your hardware out of sight beneath a bench or countertop to maximise usable working space, ensure you match your drawer model with the correct gauge under-counter mounting brackets. Metal brackets must be screwed directly into the structural framework of your counter to bear the weight of heavy-duty steel drawers filled with coin weight.
