Applications

Smart street lighting

Plug-in nodes for metering, dimming and fault reporting on LED street poles. 7-pin configuration supports cellular and RF control nodes for smart-city networks.

Photocell control

Standard 3-pin dusk-to-dawn switching for conventional street lighting. Any ANSI C136.41 compliant twist-lock photocell from any vendor locks in directly — no brand lock-in.

Smart city networks

7-pin sockets enable telemetry and monitoring nodes for city-wide lighting management. Data flows through the same twist-lock interface, eliminating separate wiring for communication.

Luminaire OEMs

Factory-fit sockets during luminaire assembly to future-proof streetlights for smart-city upgrades. The socket adds minimal cost while enabling retrofit of control nodes at any time.

Adaptive dimming programs

5-pin sockets support 0-10V/PWM dimming control from external nodes, enabling midnight dimming, occupancy-based dimming and demand-response programs without replacing the driver.

Retrofit smart upgrades

Add 5-pin or 7-pin sockets to existing luminaires during LED retrofit projects, enabling future smart-city integration without a second truck roll or pole climb.

Frequently Asked Questions

Which pin count do I need: 3, 5 or 7?

3-pin supports basic on/off photocell control. 5-pin adds 0-10V/PWM dimming. 7-pin adds telemetry wires for metering and monitoring nodes used in smart-city deployments.

Will it fit any photocell brand?

Yes. The socket follows ANSI C136.41, so any compliant twist-lock photocell or control node from any vendor locks in directly.

Can the socket withstand outdoor UV exposure?

The housing is UV-resistant and rated -40°C to +85°C for long-term pole-mounted service.

Do you supply matching surge protectors?

Yes, 10kV surge protection options are available; pair with our IP67 constant current street light drivers for a complete power solution.
