Input Connector Array: Voltage Rating 250V AC/DC, Port Count 8

Component Specifications

Definition

An Input Connector Array is a modular assembly of multiple electrical connectors arranged in a standardized pattern, typically integrated into Input Interface Modules of industrial machines. It facilitates the simultaneous connection of various input sources including sensors, control signals, power supplies, and data communication lines. The array ensures organized cable management, reduces connection errors, and provides reliable electrical contact through precision-engineered terminals with locking mechanisms. Common configurations include 4-port, 8-port, or 16-port arrays with mixed signal types (analog, digital, power).

Working Principle

The Input Connector Array operates by providing multiple isolated electrical pathways through individual connector ports. Each port contains conductive terminals (pins or sockets) that establish physical and electrical contact with mating cables. The array maintains signal integrity through proper shielding, impedance matching, and separation between high-power and low-signal circuits. Locking mechanisms (screw-type, latch, or push-pull) ensure secure connections resistant to vibration and environmental factors. Internal wiring may include common grounding buses or isolated circuits depending on application requirements.

Materials

Housing: Glass-filled nylon (UL94 V-0) or polycarbonate for flame resistance and durability. Terminals: Phosphor bronze or beryllium copper with gold or tin plating (3-15μm thickness) for corrosion resistance and low contact resistance. Insulators: PBT or LCP with CTI >600V. Seals: Silicone rubber (IP67/IP68 rating).

Frequently Asked Questions

What is the difference between an Input Connector Array and individual connectors?

An array integrates multiple connectors into a single housing with shared mounting and sealing, improving space efficiency, cable management, and installation speed compared to separate connectors.

Can Input Connector Arrays be customized for specific signal types?

Yes, arrays can be configured with mixed port types (e.g., combining power, analog, and digital ports) and customized pin assignments to match specific machine requirements.

How are these arrays protected against environmental factors?

They feature IP67/IP68 rated seals, corrosion-resistant materials, and often include protective caps for unused ports to prevent contamination.
