Product Details

Features & Specifications	Technical Advantages	Operational & Business Benefits
32-Pin Hybrid Power & Signal Design	Combines 6x #16 power contacts and 26x #20 signal contacts in a single high-density body.	Significant Space Savings: Reduces the total footprint and weight of wiring harnesses, allowing for more compact PDU and battery pack designs.
B-Key Specific Polarization	Features a unique B-Key physical orientation to prevent mating with A or C key receptacles.	Zero Error Assembly: Eliminates the risk of cross-mating in complex systems where multiple similar connectors are used, preventing electrical damage.
IP67/IP68 Environmental Protection	Maintains a high-performance seal even when submerged in 1-meter deep water for 48 hours.	High Reliability in Harsh Conditions: Protects sensitive signal circuits from moisture, dust, and vibrations, ensuring zero downtime in mining or marine environments.
Ergonomic Latch Lock Mechanism	Features a robust mechanical locking clip designed for easy manual handling and audible feedback.	Secure Connection & Efficiency: Ensures a vibration-proof mate with a clear click, reducing the time required for maintenance and visual inspections.

Q1: What is the difference between HC18B-S32 and HC18B-S32-2?

A: The HC18B-S32-2 is an upgraded version that includes a Secondary Lock (CPA – Connector Position Assurance). While the standard HC18B-S32 provides a secure latch, the “-2” version adds an extra layer of safety to ensure the connector cannot be dislodged under extreme vibration.

Q2: Can I use different keys (A, B, or C) together?

A: No, the polarization keys are designed as a safety feature. The HC18B-S32 (B-Key) will only mate with a B-Key receptacle. This is intended to prevent mis-connection in devices that have multiple identical 32-pin ports for different functions.

Q3: Which terminals are compatible with the HC18B-S32 plug?

A: You will need #16 Power Female Contacts (for the 6 larger cavities) and #20 Signal Female Contacts (for the 26 smaller cavities). We recommend using Amphenol genuine gold-plated contacts to ensure maximum conductivity and IP sealing performance.
