Tools that assist in the installation of composite sensor adapter cables serve as a critical safeguard for ensuring reliable connections, effective shielding, and system stability. Each tool corresponds to a specific stage of the installation process; when used correctly, they can significantly reduce the risk of human error and latent faults.
I. Core Tools and Their Functions
1. Multimeter:The "First Line of Defense" for Electrical Performance
Functions:
Continuity Testing: Confirms whether each wire core is conductive; resistance value should be < 0.5Ω.
Insulation Testing: Checks the insulation resistance between wires, as well as between wires and the shielding layer; values should be > 500MΩ (requires a megohmmeter function).
Shielding Continuity Detection: Measures the total resistance of the shielding layer along its entire length; values should be < 0.1Ω/m.
When to Use: Testing is mandatory both before and after installation to prevent "operating with faults."
Recommended Models: Fluke 15B+, UNI-T UT139C (features data hold and backlight).
2. Torque Wrench: The "Precision Controller" for Reliable Connections
Functions:
Precisely controls the tightening torque of locking nuts, preventing overtightening (which causes stripped threads or cracked housings) or undertightening (which leads to loosening due to vibration).
Recommended Industrial Standard: The locking torque for M12 nuts is 0.6–1.0 N·m.
Key Usage Points:
After hand-tightening, apply additional force using the torque wrench for a final quarter-turn.
Perform periodic calibration to ensure accuracy remains within ±5%.
Applicable Scenarios:High-reliability systems such as automotive production lines, wind power equipment, and rail transit systems.
3. Wire Stripper: The "Surgical Scalpel" for Precision Handling
Functions:
Precisely strips away the outer jacket (10–15 mm) without damaging the internal shielding layer.
Strips the insulation from the individual wire cores (2–3 mm), preventing broken copper strands or poor crimping connections.
Precautions:
Do not use standard electrician's pliers, as this can easily damage the internal core;
Select the appropriate setting based on the wire gauge; common specifications support wire sizes ranging from 0.14 to 2.5 mm².
Advanced Tool: Specialized wire strippers featuring a shielding-layer folding function, designed to enhance termination efficiency for M12 and M8 connectors.
4. Anti-Static Wrist Strap:The "Invisible Guardian" of Precision Electronics
Function:
Safely channels static electricity from the human body to ground, preventing electrostatic discharge (ESD) from damaging sensitive internal circuitry within sensors;
Particularly suitable for applications involving medical equipment, semiconductor testing, and high-precision MEMS sensors.
Usage Guidelines:
Wear the strap prior to installation, and connect the grounding terminal to an anti-static workbench or a dedicated ground point;
The internal resistance value should be approximately 1 MΩ to ensure that static current is safely dissipated without posing a shock hazard to the user.
Complementary Measures:** Use in conjunction with anti-static mats and ionizers to establish a comprehensive ESD protection system.
