HIMA Z7126/6705/C5

HIMA Z7126 (also known as Z6705 or C5) is a safety-focused circular cable connector specifically designed for industrial automation systems. It features a 5-pin (or 17-pin) circular connection structure and complies with the Safety Integrity Level (SIL) 3 as defined in IEC 61508, enabling reliable signal and power transmission in potentially explosive hazardous areas. This product is positioned as a high-reliability, environment-resistant fieldbus/safety I/O interface.

Key Technical Specifications

• Number of Channels: 2 channels
• Safety Level: SIL 3 (compliant with IEC 61508)
• Operating Temperature Range: -20 °C ~ +60 °C
• Ingress Protection Rating: IP67 (dust-tight and waterproof), suitable for harsh industrial environments
• Material: High-grade plastic housing + nickel-plated brass contacts (corrosion-resistant and impact-resistant)
• Dimensions/Weight: Approximately 4.1 cm × 19 cm × 12.9 cm, weighing around 0.6 kg

Product Features

1. Safety & Reliability: Complies with SIL 3 standards and incorporates redundant design, making it suitable for safety control in hazardous areas.
2. High Protection Performance: With an IP67 rating, it is dust-tight and waterproof, allowing long-term operation in humid, dusty, or chemical-exposed environments.
3. Easy Installation & Maintenance: Modular structure supports DIN rail or panel mounting; the connector enables easy plugging and unplugging, reducing downtime.
4. Strong Compatibility: Works with various industrial automation systems (PLC, DCS, fieldbus) and supports multiple signal types (analog, digital).
5. Environmental Resistance: Nickel-plated brass contacts and high-strength plastic housing ensure corrosion resistance and vibration resistance, making it ideal for industries such as petrochemicals, iron and steel, and pharmaceuticals.

Structure & Composition

• Housing: High-strength plastic with metal reinforcements, providing mechanical protection.
• Connector: Circular 5-pin or 17-pin plug with internal nickel-plated brass contacts to ensure low contact resistance.
• Internal Circuitry: Includes safety redundancy circuits, analog/digital conversion modules, and filtering/protection components.
• Mounting Accessories: DIN rail clips, screws, and sealing gaskets for quick on-site fixation.

Typical Application Fields

1. Safety Control in Hazardous Environments: Safety instrumented systems (SIS) in high-risk industries such as petrochemicals, natural gas, pharmaceuticals, iron and steel, and cement production.
2. Industrial Automation: Signal and power connection for PLCs, DCS, and fieldbuses (e.g., Profibus, Profinet, Modbus).
3. Process Monitoring: Acquisition and output of analog signals for process variables like temperature, pressure, and flow rate.
4. Power Supply: Provides reliable 24 V DC power for HIMA safety controllers and I/O modules (e.g., F7126 series).

Installation & Maintenance Guidelines

Pre-Installation Check

• Verify that the connector model and pin count match the system requirements.
• Inspect the housing for damage and ensure the sealing gasket is intact.

Fixation Method

• Use DIN rail or panel screws for fixation; ensure the connector is placed horizontally to avoid uneven stress.

Wiring

• Connect signal wires and power wires in accordance with the wiring diagram; use anti-twist cable harnesses.

Protection Inspection

• After installation, check the integrity of the IP67 seal; use waterproof rubber rings if necessary.

Regular Maintenance

• Conduct visual inspections every 6–12 months to remove dust and corrosive substances.
• Measure the resistance of contacts to ensure low contact impedance.

Troubleshooting

• If signal anomalies occur: first check cable integrity and connector tightness, then use an oscilloscope or multimeter to verify electrical parameters.
