Cables & Connectors

In electrical automation, cables and connectors play crucial roles in ensuring reliable and efficient communication, power delivery, and control within automated systems. At John Henry Foster, we carry the safe and reliable cables and connectors to fit any application.

Cables
Power Cables
Purpose: Deliver electrical power to various components and devices.
Types: Low-voltage, medium-voltage, and high-voltage cables, depending on the application requirements.
Insulation: Typically insulated with PVC, XLPE, or rubber for safety and durability.

Control Cables
Purpose: Transmit control signals from controllers to actuators, sensors, and other devices.
Features: Often shielded to protect against electromagnetic interference (EMI).
Types: CY (screened flexible control cables), YY (unshielded flexible control cables), SY (steel wire braided control cables).

Data Cables
Purpose: Facilitate data communication between devices such as PLCs (Programmable Logic Controllers), HMIs (Human-Machine Interfaces), and computers.
Types: Ethernet cables (Cat5e, Cat6, Cat6a), Profibus cables, Modbus cables, and fiber optic cables.
Features: High-speed data transmission and often shielded for EMI protection.

Instrumentation Cables
Purpose: Used for transmitting low-level signals in monitoring and control applications.
Types: Twisted pair cables, coaxial cables, and triad cables.
Features: High accuracy and low noise, often shielded to prevent signal interference.

Servo and Motor Cables
Purpose: Connect servo drives and motors, providing power and feedback signals.
Features: Flexible, durable, and capable of handling high currents and frequent motion.
Connectors
Power Connectors
Purpose: Connect power supply units to various devices.
Types: IEC connectors, Molex connectors, and industrial power plugs.
Features: High current rating, robust construction, and secure locking mechanisms.

Signal Connectors
Purpose: Connect control signals between devices.
Types: D-sub connectors, M12 connectors, and terminal blocks.
Features: Secure connections, often with screw or spring clamp terminals.

Data Connectors
Purpose: Facilitate data communication in automation systems.
Types: RJ45 connectors for Ethernet, USB connectors, and fiber optic connectors (LC, SC, ST).
Features: High-speed data transfer, often shielded to prevent data loss and interference.

Sensor/Actuator Connectors
Purpose: Interface sensors and actuators with control systems.
Types: M8 and M12 connectors, used extensively for field wiring in industrial environments.
Features: Rugged design, waterproof (IP-rated) for harsh environments.

Circular Connectors
Purpose: Provide versatile connections for power, signal, and data.
Types: M23, M40, and other circular connectors.
Features: Robust, often used in environments requiring high reliability and durability.
