1 — Background & Key Use Cases
Device overview: what the component is and where it's typically used
Point: The C112 10A024 050 10 belongs to the Amphenol Tuchel C112 series of high-performance M12 industrial circular cable assemblies. Evidence: According to the official datasheet PDF, the part code translates as a female straight M12 A-coded connector with 4 poles, 24 AWG conductor sizing, and a 5.0-meter PUR (Polyurethane) jacketed cable. Explanation: This series is highly valued in industrial sensor-actuator buses, automated production lines, robotics, and machine tool configurations. Systems design engineers select this family due to its IP67 ingress protection rating, excellent chemical resistance to oils and coolants, and dense circular form factor that saves cabinet and routing space.
Quick-spec snapshot: essential at-a-glance parameters
Point: Key absolute limits must be validated early during system-level power budget planning. Evidence: These values are extracted directly from the "Technical Data" and "Electrical Characteristics" sections of the C112 documentation. Explanation: Below is a highly consolidated parameter matrix for immediate review prior to CAD layout.
| Parameter | Value (extracted from datasheet) | Table/Figure ref |
|---|---|---|
| Rated current / continuous | 4 A per contact @ 40°C | Electrical Characteristics — Table 1 |
| Voltage rating / Vmax | 250 V AC/DC (for 4-pole configuration) | Absolute Maximum Ratings — Table 2 |
| Package / footprint | M12 Female Straight (A-Coded), Circular Knurled Nut | Mechanical Assembly Drawing |
| Operating temp range | -25°C to +80°C (flexible installation) / -40°C to +80°C (fixed) | Climatic Characteristics — Section 3.2 |
| Key thermal RθJA / RθJC | Refer to local ambient derating curves (VDE 0298 part 4) | Thermal Performance Curves |
2 — Full Electrical Specifications & Performance
Absolute maximum ratings & operating limits
Point: Violating absolute ratings can lead to localized dielectric breakdown or thermal runaway of the PUR insulation. Evidence: The C112 datasheet outlines strict limits on peak operating limits under standard atmospheric conditions. Explanation: The absolute maximum voltage limit is 250V AC/DC. Exceeding this can cause tracking currents across the contact carrier. When planning power distribution networks, engineers must apply safety derating: for instance, limiting continuous current to 80% (3.2A) when operating ambient temperatures approach the +80°C maximum limit, preserving the internal solder joint and wire insulation integrity.
Electrical characteristics, typical values and graphs to include
Point: Translating datasheet curves into safe operating envelopes prevents contact wear and voltage sag. Evidence: Refer to the contact resistance specs (typically < 5 mΩ) and the insulation resistance specs (> 10^9 Ω) in the datasheet. Explanation: The datasheet specifies typical values versus guaranteed limits. For prototyping, engineers must design around the maximum contact resistance limit (10 mΩ) to calculate worst-case voltage drop over the 5.0m cable length. During lab validation, mock the full 4A load and monitor the connector temperature rise to verify it aligns with the vendor's thermal derating curves.
3 — Pinout, Package & PCB Footprint
Pin-by-pin breakdown (pinout details)
Point: The M12 female straight connector utilizes standard A-coding to prevent cross-mating with network or power-key variants. Evidence: Pin mappings are mapped directly from the mechanical mating face schematic in the C112 datasheet. Explanation: This pinout list ensures correct routing to the field junction box or sensor controller board.
| Pin # | Wire Color | Function | Electrical Notes | Typical Connection |
|---|---|---|---|---|
| 1 | Brown (BN) | VCC / Power Feed | High-current path, up to 4A continuous | System +24V DC Rail |
| 2 | White (WH) | I/O Signal / NC | Configurable auxiliary analog/digital input | PLC Discrete Input Card |
| 3 | Blue (BU) | GND / Return | Common ground reference return path | Power Supply 0V Return |
| 4 | Black (BK) | Switching Output | Control signal / PWM actuator trigger | Sensor Load Signal Wire |
Note: Standardized M12 female pinouts demand clean wire stripping. Ensure ESD/surge protection diodes are placed near the measurement pin connections on the receiving PCB terminal board to handle common-mode noise.
Mechanical drawing & recommended PCB land pattern
Point: Correct mating clearance depends on precise CAD library integration of the mating panel bulkhead or PCB receptacle. Evidence: Refer to the Amphenol C112 series mechanical mounting drawing for thread specs (M12 x 1, knurled locking ring). Explanation: If you are integrating a mating panel-mount PCB connector, verify that your board-level land pattern uses the recommended footprint diameter (typically 1.3mm to 1.5mm holes for solder tails). Include a 15mm clearance zone radially around the connector centerline to allow standard torque wrench tools to access and tighten the knurled metal nut to its nominal 0.6 Nm rating.
4 — Application Notes & Reference Circuits
Typical application circuits to reproduce and annotate
Point: Industrial inductive loads require snubber configurations to protect the C112 cable integrity from back-EMF spikes. Evidence: Recommended sensor interface schematics in the datasheet highlight decoupling and transient suppression layouts. Explanation: When routing a proximity sensor via the C112 10A024 050 10 cable assembly, place a TVS diode (e.g., SMAJ24A) directly across the VCC (Pin 1) and GND (Pin 3) nodes at the control cabinet entry terminal. Decouple high-frequency switching noise with a 100nF ceramic capacitor close to the receiver inputs.
Practical design tips & testing checklist
- Cable Bend Radius: Do not exceed the minimum dynamic bend radius of 10x outer cable diameter (approx. 50mm) in motion-centric drag chains.
- Torque Limits: Hand-tighten the M12 plastic/metal mating ring, or use a calibrated torque wrench set to exactly 0.6 Nm to maintain the IP67 seal.
- Thermal Stitching: On the PCB receiver board, ensure ground traces utilize thermal-relief stitching vias to distribute heat away from the pin solder terminals.
- Environmental Shielding: Keep high-voltage AC lines isolated from sensor signal lines run through the C112 10A024 050 10 to prevent EMI cross-talk.
5 — How to Obtain & Verify the Datasheet PDF + Sourcing Tips
Finding and validating the official C112 10A024 050 10 datasheet PDF
Point: Relying on outdated third-party datasheet mirrors can lead to fatal wiring mismatches in field prototypes. Evidence: Document authenticity is confirmed by tracking the revision control index (e.g., Rev 2.1) and verification marks. Explanation: To find the original document, search for "C112 10A024 050 10 datasheet PDF" directly on Amphenol Sine Systems or Amphenol Tuchel Industrial portals. Check that the document footer references "Amphenol Tuchel Industrial GmbH" and that the product description explicitly states "PUR, 4x24AWG, 5m" to confirm you are not referencing PVC or custom-length variants.
Procurement, compliance & lot verification checklist
Point: Ensuring supply chain traceability protects industrial deployment lots from counterfeit or low-temp materials. Evidence: Sourcing standards map directly to Amphenol's material qualification sheets. Explanation: When purchasing, verify that the vendor provides RoHS, REACH, and UL/CSA flammability classification certificates. For safety-critical field trial runs, procure a small batch of 5–10 units from certified distributors (e.g., Mouser, DigiKey, or Arrow) to test insulation resistance and cable flexibility at low-temperature thresholds before freezing the Bill of Materials (BOM) for full-scale production.
Summary
- Critical Reference: The C112 10A024 050 10 datasheet acts as the singular source of truth for mechanical dimensions, absolute limits, and IP ratings—use the compiled parameters to lock down system designs early.
- Pinout Alignment: Follow the A-coded female pin mapping (Brown/White/Blue/Black) exactly to eliminate system-level wiring errors that could damage sensitive automation controllers.
- Prototyping Strategy: Enforce a 20% electrical safety margin, apply proper snubber protection for inductive sensor circuits, and respect the 10x cable bend radius during harness routing.
- Sourcing Rigor: Always verify the Amphenol Tuchel logo, revision date, and PUR material markings on incoming cable batches to maintain regulatory compliance and high-flex system durability.
Final Action: Download the official verified C112 10A024 050 10 datasheet PDF and validate the current-carrying limits against your prototype's thermal load profile before signing off on PCB and system fabrication.
