Electrical Interfaces

Electrical Connectors

Electrical connectors create repeatable interfaces between lighting fixtures, circuit boards, power supplies, sensors, controls, wiring, and industrial equipment.

Connectors simplify assembly, installation, replacement, and troubleshooting by allowing electrical interfaces to be separated without permanently removing wiring. The correct connector depends on the electrical, mechanical, and environmental requirements.

Power Connections

Carrying Electrical Power to the Lighting System

Power connectors should support the required voltage and current while providing suitable insulation, mechanical retention, polarity control, and conductor termination.

Legacy resources include power connectors as one category within industrial connector technology.

Industrial electrical connectors and electronics

Signal Connections

Connecting Sensors and Controls

Control and sensor wiring may require additional contacts beyond the main power connection. Multi-pin connectors can package several functions within one removable interface.

Electrical connectors are used across many industrial systems to create detachable power and signal connections.

Board Interfaces

PCB-Mounted Connectors

Board connectors can interface directly with wiring harnesses or adjacent electronic modules. Placement should account for mating direction, enclosure clearance, cable bend radius, and service access.

PCB Assemblies

Industrial Exposure

Dust, Moisture, Oils and Vibration

Connectors installed near industrial processes may experience contamination, vibration, repeated connection cycles, washdown, or mechanical impact.

Housing, seals, locking method, strain relief, contact system, and mounting should be selected around realistic operating conditions.

Mechanical Retention

Preventing Accidental Disconnection

Latches, threaded couplings, clips, locking tabs, friction features, or other retention systems can keep connectors mated during vibration and normal machine operation.

Selection

Electrical Connector Design Factors

Voltage & CurrentMatch connector electrical capability to the circuit.
Contact CountProvide enough circuits for power, signals, sensors, and controls.
PolarityPrevent incorrect mating where circuit orientation matters.
RetentionUse suitable locking for vibration and handling.
EnvironmentConsider moisture, dust, chemicals, and mechanical exposure.
Service AccessLeave adequate space for mating and removal.
