Datalogic 90A051891 RS-232 Coiled Cable
Overview
The Datalogic 90A051891 is a genuine OEM RS-232 serial cable built to Datalogic's original manufacturing specifications. The coiled design reduces cable clutter in warehouse, distribution, and retail environments where multiple scanners and mobile computers operate in close proximity. The 9-pin female connector ensures correct pin configuration without requiring adapters, eliminating a common source of integration errors when deploying large Datalogic device fleets.
Key Features
- OEM Construction: Manufactured to Datalogic engineering standards — skipping third-party alternatives removes compatibility risk and simplifies warranty compliance across enterprise deployments.
- RS-232 Serial Protocol: Delivers reliable RS-232 connectivity for Datalogic barcode scanners, mobile data terminals, and enterprise handheld computers that require serial communication with host systems or docking stations.
- 9-Pin Female Connector: Female 9-pin DB9 connector ensures the correct mating interface without requiring gender changers — reduces field troubleshooting time and prevents pin misalignment issues.
- Coiled Cable Design: Coiled format compresses unused cable length, reducing tangles and clutter — particularly valuable in dense scanning stations or warehouse pick-to-light environments where cable management affects operator efficiency.
- Signal Integrity Shielding: Proper shielding prevents electromagnetic interference that can corrupt serial data — critical when running cables parallel to power lines or high-frequency wireless equipment in industrial facilities.
- Durable Connector Performance: Genuine OEM connectors are rated for continuous operational use and repeated mating cycles, avoiding the premature failures common with lower-cost alternatives that degrade after hundreds of docking cycles.
Integration & Compatibility
The 90A051891 is certified for use with Datalogic-compatible enterprise scanning and mobile computing hardware. Genuine OEM status ensures this cable maintains warranty coverage for connected devices and supports rapid replacement in high-availability warehouse and distribution environments. Organizations managing Datalogic device inventories should stock this cable to minimize downtime during equipment rotation or repair cycles.
If you operate a large barcode scanner fleet or manage multiple Datalogic mobile computers across shifts, having certified OEM cables on hand prevents emergency supply-chain delays. Pairing with enterprise mobile data terminals requires reliable serial connectivity — third-party cables introduce unquantified risk.
Frequently Asked Questions
Q: Is the Datalogic 90A051891 compatible with all Datalogic scanners?
A: The 90A051891 is compatible with Datalogic enterprise scanning and mobile computing devices that feature a 9-pin female RS-232 serial port. Verify your device's connector type before ordering — some newer Datalogic models may use USB or other proprietary interfaces.
Q: Can I use this cable with third-party barcode scanners?
A: The 90A051891 is manufactured specifically for Datalogic equipment. While the RS-232 9-pin female connector is a standard interface, using it with non-Datalogic devices may void the original equipment's warranty. Consult your device documentation before cross-deployment.
Q: What is the cable length?
A: The coiled design compresses the working length for space efficiency. The exact extended length is not specified in the product documentation — contact the manufacturer or your authorized distributor for precise measurements if cable run length is critical to your installation.
Q: Does this cable include a warranty?
A: Genuine Datalogic OEM cables are backed by manufacturer warranty. Specific warranty terms should be confirmed at the point of purchase.
Q: How do I know if my scanner has a 9-pin female connector?
A: Inspect the serial port on your Datalogic device. A 9-pin female connector has nine small holes arranged in two rows. If your device has a different connector type (such as a circular mini-DIN connector), this cable will not fit.

The Datalogic 90A051891 is a straightforward but essential piece of infrastructure for any warehouse or retail operation running a mature Datalogic device estate. If you're managing scanners or mobile terminals across multiple shifts, this OEM cable eliminates the reliability gamble that comes with generic RS-232 replacements. The coiled construction is not a gimmick — it genuinely reduces cable fatigue at the connector and keeps your scanning stations organized when real estate is tight.
Technical Highlights:
- 9-Pin Female DB9 Connector: Guarantees correct pin alignment without adapters. Field experience shows that misaligned or corroded third-party connectors account for a disproportionate share of scanner integration failures in high-volume deployments.
- Coiled Design: Reduces unused cable length, preventing loop entanglement that can pull on mating connectors during busy pick cycles. Matters more than you'd expect in dense scanning zones.
- Signal Shielding: RS-232 is an analog protocol susceptible to electromagnetic noise. Proper shielding on the 90A051891 prevents data corruption that typically manifests as intermittent barcode read failures or terminal dropout — expensive to diagnose after the fact.
Deployment Considerations:
- This cable is serial-only — no power delivery. Confirm your Datalogic device draws power from a separate supply or docking station.
- Common gotcha: Not all Datalogic models use 9-pin female RS-232. Verify your device's connector before ordering. Migration to USB-based scanners means this cable has a limited lifespan in your fleet.
For distribution and warehouse integrators deploying or refreshing Datalogic barcode infrastructure, the 90A051891 is a low-cost insurance policy against connector-related downtime. Stock a few for emergency replacements and you'll avoid the cost of expedited overnight shipping when a scanner connector fails at 2 AM on a peak day.
