HARTING 21038811805: Premium M12-8 Male Plug Housing for Industrial Connectivity Solutions
The HARTING 21038811805 represents the gold standard in circular connector housings, specifically engineered for mission-critical applications requiring uncompromising reliability. As part of HARTING's renowned Han industrial connector series, this M12-8 male plug housing delivers exceptional mechanical stability and electrical performance in demanding environments. This comprehensive guide explores every technical aspect of this connectivity solution to help engineers and procurement specialists make informed decisions.
Product Overview & Specifications
This 8-position male plug housing belongs to the M12 connector series (IEC 61076-2-101/104 compliant), featuring a threaded coupling mechanism that ensures vibration-resistant connections. The silver-colored zinc die-cast housing provides both EMI shielding and corrosion resistance, while the integrated strain relief prevents cable damage in high-flex applications.
Key Technical Specifications:
- Shell Size: M12-8 (standardized per IEC 61076-2-101)
- Current Rating: 4A per contact (at 50 C)
- Voltage Rating: 250V AC/DC
- Contact Resistance: 5m
- Insulation Resistance: 1000M (500VDC)
- Dielectric Strength: 1500V AC (50Hz for 1 minute)
Advanced Design Features
1. Robust Mechanical Construction
The housing utilizes heavy-duty zinc alloy with chrome plating, achieving both IP65 and IP67 protection ratings when properly mated. The threaded coupling mechanism requires only 0.5 N m torque for secure locking, while the 360 shielding ensures complete EMI/RFI protection.
2. Precision Contact System
Engineered for crimp termination (accepts AWG 24-20 wires), the contact chambers feature:
- Gold-plated male pins for low insertion force ( 2.5N per contact)
- PA66 insulation material with UL94 V-0 flame rating
- Color-coded sealing grommets for easy polarity identification
3. Enhanced Cable Management
The integrated strain relief system accommodates cable diameters from 4-8mm, with:
- Adjustable clamping force via screw mechanism
- Anti-rotation features to prevent cable twisting
- Integrated sealing for moisture protection
