NI BNC-2110 – Shielded BNC Terminal Block for 68‑pin NI DAQ Connectivity

The NI BNC-2110 is a bench‑top, shielded BNC terminal block that makes it fast to connect sensors and test signals to 68‑pin NI multifunction DAQ devices. From my experience, teams pick it when they want clean, reliable BNC I/O without building custom breakouts. You get straightforward BNC connections for analog input/output and timing/trigger lines, plus a single 68‑pin interface back to your DAQ. It typically reduces wiring time, keeps benches tidy, and seems to help with signal integrity in many lab setups.

Key Features

• Direct BNC connectivity – Quickly route analog and timing signals using standard BNC cables; no soldering or adapters in most cases.
• 68‑pin DAQ interface – Connects to NI X Series / M Series–style 68‑pin devices through a single cable, simplifying the test bench.
• Shielded enclosure – The metal housing and grounding points typically help reduce noise pickup for low‑level measurements.
• Labeled I/O mapping – Clear channel labeling makes it easier for technicians to avoid wiring mistakes during reconfigurations.
• Bench‑top or panel use – Sits securely on a bench; can be panel mounted if you prefer a fixed ATE layout.
• No external power – Passive breakout design; just connect your DAQ cable and you’re ready.

Technical Specifications

Application Fields

You’ll typically see the BNC-2110 in R&D labs, university teaching labs, production test benches, and benchtop ATE where BNC cabling is the standard. It’s handy for sensor bring‑up (voltage output sensors, function generator feeds), analog verification, product characterization, and timing/trigger distribution between instruments. One thing I appreciate is how quick it makes reconfiguring channels during a debug session—no need to open a cabinet or touch ribbon headers.

Advantages & Value

• Lower integration effort – Standard BNC lets you reuse existing lab cables and fixtures.
• Compatibility – Works with many NI 68‑pin DAQ families, reducing risk when you upgrade PC cards or USB DAQs.
• Signal integrity – Shielded, short run to the DAQ device typically means less noise pickup compared with ad‑hoc breakouts.
• Serviceability – Clear labeling and durable connectors make it easier for technicians to maintain and swap setups.
• Cost control – Compared to custom panels, it reduces build time and rework—useful in pilot lines and EDU labs.

Installation & Maintenance

• Environment – Place on a stable, ventilated bench; avoid conductive debris and liquids. For cabinets, allow airflow around the unit.
• Wiring – Use quality BNC coax appropriate for your bandwidth; keep runs short. Connect the chassis/shield to a known ground to minimize loops.
• DAQ Cable – Use NI shielded 68‑pin cables (e.g., SH68‑68‑EP) for best noise performance; secure strain relief to prevent connector stress.
• Safety – Signal‑level use only; do not apply hazardous voltages. Observe ESD precautions when handling connectors and DAQ interfaces.
• Routine care – Periodically inspect BNC jacks for wear, clean with lint‑free swabs and isopropyl alcohol, and verify ground continuity. No calibration is required for this passive accessory.

Quality & Certifications

• CE compliant; RoHS compliant; WEEE applicable
