Key Features
Overview
The TC2050-CLIP provides a simple, effective solution for maintaining stable connections between TC2050-NL "no legs" programming cables and target PCBs during debugging and programming operations. This precision-manufactured clip attaches to the cable's alignment pins from beneath the PCB, creating a secure mechanical retention that enables hands-free debugging sessions.
Designed for engineers working with space-constrained designs, the TC2050-CLIP works exclusively with Tag Connect's minimal-footprint TC2050-NL connector system. The clip accommodates PCB thicknesses up to standard 1.6mm whilst maintaining reliable spring-pin contact pressure for consistent electrical connections.
The clip's compact design ensures it doesn't interfere with surrounding components whilst providing the mechanical stability required for extended programming sessions, production testing, or firmware development activities.

Hands-Free Programming and Debugging Solution
The TC2050-CLIP is a precision-engineered retaining clip designed to securely hold TC2050-NL ("No Legs") cables in place on target PCBs during programming, debugging, and testing operations. This compact solution addresses the challenge of maintaining stable connections when using Tag Connect's space-saving no-legs connector footprint.
Key Operating Principle
The TC2050-CLIP operates by attaching to the alignment pins of the TC2050-NL cable from underneath the target PCB. Once pressed onto the alignment pins, it provides mechanical retention that keeps the cable securely connected during extended debugging sessions, allowing engineers to work hands-free whilst maintaining reliable electrical connections.
Wiring Quick-Start
Installation requires no soldering or permanent modifications to your target board:
1. Connect TC2050-NL cable to target PCB footprint 2. Align TC2050-CLIP with cable alignment pins from PCB underside 3. Press clip firmly onto alignment pins until secured 4. Verify stable connection with gentle cable movement test 5. Begin programming or debugging operation PCB Footprint Requirements
The clip works with the standard TC2050-NL footprint, which requires only 0.03 square inches of PCB space - equivalent to two or three SMT resistors. The footprint consists of ten contact pads arranged in two rows of five, plus two alignment holes for the cable's positioning pins.
| Parameter | Specification |
|---|---|
| Footprint Size | 0.43" x 0.20" (10.9mm x 5.1mm) |
| Contact Pad Diameter | 0.04" (1.0mm) |
| Alignment Hole Diameter | 0.04" (1.0mm) |
| Pin Pitch | 0.05" (1.27mm) |
| Row Spacing | 0.1" (2.54mm) |
Compatibility Matrix
The TC2050-CLIP is specifically designed for use with Tag Connect's TC2050-NL series cables and their compatible adapters:
| Cable Model | Connector Type | Compatibility |
|---|---|---|
| TC2050-IDC-NL | 10-pin ribbon (0.1") | ✓ Full compatibility |
| TC2050-IDC-NL-050 | 10-pin ribbon (0.05") | ✓ Full compatibility |
| TC2050-IDC-NL-430 | MSP430 RJ12 | ✓ Full compatibility |
| TC2050-IDC | 10-pin legged | ✗ Not compatible |
Production Programming Applications
The TC2050-CLIP excels in production environments where rapid, repeated connections are required. The clip enables automated test equipment to maintain consistent connections during high-volume programming cycles whilst eliminating the need for expensive custom fixtures or pogo pin assemblies.

Questions and Answers
-
How Do I Install the TC2050-CLIP on My Setup?
Fit it from underneath the PCB onto the three alignment pins of the TC2050-NL cable.
1Connect your TC2050-NL cable to the target PCB footprint.2From underneath the PCB, align the clip with the cable's alignment pins.3Press the clip on until it grips the pins. Tag-Connect gives no fitting instructions, but one pin on the clip is angled by 5 degrees to improve its grip. -
What Debuggers and Programmers Work with TC2050-CLIP Setups?
The clip only holds the cable, so it works with whichever debugger your TC2050-NL setup supports. Tag-Connect pairs the TC2050-ARM2010 with a TC2050-IDC-NL cable for these tools:
Debugger Setup SEGGER J-Link TC2050-ARM2010 with TC2050-IDC-NL and TC2050-CLIP-3PACK ST-LINK/V2 TC2050-ARM2010 with TC2050-IDC-NL and TC2050-CLIP-3PACK ARM Keil ULINK TC2050-IDC-NL-050, which Tag-Connect describes as equivalent to TC2050-ARM2010 with TC2050-IDC-NL on the ULINK2 20-pin 0.1 in header -
Is the TC2050-CLIP Reusable Across Different Projects?
You can refit it, but Tag-Connect describes it as a temporary hold: over time the clips may lose some grip, and they are easily misplaced when working at the desktop. Tag-Connect recommends keeping a few spares.
-
What Happens If I Lose My TC2050-CLIP During Development?
Replace it from a TC2050-CLIP-3PACK, which Tag-Connect supplies as a pack of three. Tag-Connect recommends keeping a few spares because the clips are easily misplaced.
-
Can the TC2050-CLIP Interfere with Nearby PCB Components?
It sits on the underside of the board, so it clears top-side parts, but allow about 6.7 mm of free space below the footprint for the clip and pins.
Clip dimension Value Clip board 10.922 mm x 5.080 mm Board thickness 0.914 mm Pin length 6.223 mm Overall depth below the PCB About 6.7 mm -
What Is the TC2050-CLIP and How Does It Work?
The TC2050-CLIP is a retaining clip that holds TC2050-NL "no legs" cables in place on the target PCB. It attaches to the cable's alignment pins from underneath the PCB, so you can debug and program hands-free.
-
Which Tag Connect Cables Are Compatible with the TC2050-CLIP?
The TC2050-CLIP works with all TC2050-NL series cables, including:
- TC2050-IDC-NL
- TC2050-IDC-NL-050
- TC2050-IDC-NL-050-ALL
- TC2050-IDC-NL-430
It does not fit legged versions such as the TC2050-IDC.
-
Does the TC2050-CLIP Require Any Modifications to My PCB?
No. The TC2050-CLIP needs no soldering or permanent changes to your PCB. It clips onto the TC2050-NL cable's alignment pins from the underside of the board for temporary retention.
-
What PCB Thickness Does the TC2050-CLIP Support?
Tag-Connect does not publish a PCB thickness limit for the clip. The drawing gives the clip dimensions only, so check the fit on your own board stack-up.
-
Can I Use the TC2050-CLIP for Production Programming?
No. The clip is for temporary, hands-free use at the bench and can lose grip over time. For a production fixture use the TC-MOUNT-10 bracket, which mounts the no-legs connector permanently in the fixture. For short one-off production programming the no-legs cable is simply held by hand.
