Slot Reader for Access Control

The UNITECH MS146-IRCB00-SG is a multidirectional infrared barcode slot reader built for time‑and‑attendance, security and access‑control systems. It reads badges, cards and forms through a wide slot that accepts many card sizes. The sealed optical assembly resists dust, dirt, water spills and repeated 5‑foot drops to concrete. An RS‑232 cable is included; the power adapter is sold separately.

Suits ID‑Card Check‑In, Not General Scanning

This unit fits libraries, fitness centres and workplaces that need reliable check‑in or check‑out of ID cards and barcodes protected by black anti‑photocopy panels. It does not suit retail point‑of‑sale scanning of merchandise labels, handheld inventory work or any application that requires a wireless or USB connection.

RS‑232 Interface Decides Compatibility

The reader communicates only through an RS‑232 serial port, so the host system must provide a matching COM port or a verified serial‑to‑USB adapter. If the target PC or controller lacks a native RS‑232 connection, this model will not integrate without additional hardware.

Questions about this item

How often should the infrared scan window be cleaned to keep the 6-mil resolution reliable?

The sealed optical system resists dust and spills, so a quick wipe with a lint-free cloth whenever cards leave residue is usually enough.

At the top scan speed of 30 inches per second, what limits continuous throughput first?

The RS-232 serial link and host software processing become the bottleneck before the reader's own 27-inch-per-second decode rate.

Does the unit run warm or draw extra power when left on all day at a check-in desk?

It operates from 0 to 50 °C with no fan, so heat output is minimal and power draw stays low during constant idle or scanning.
