Stem Mount Photo Control Sensor

The Intermatic EK4163S is a stem-mount electronic photo control designed for outdoor lighting fixtures. It targets installers and property managers who need a long-life dusk-to-dawn switch for LED, tungsten or ballast-driven loads. The unit carries a 10 to 20 year service life expectancy to match modern LED fixture lifespans. It suits new construction or retrofit projects where maintenance-free operation is a priority.

Wiring and Load Compatibility

The sensor connects via 6 inch leads and operates on 105 305 VAC circuits. It handles 1000W tungsten, 1800 VA magnetic ballast and 6 AMP electronic ballast or LED driver loads. Testing follows NEMA 410 to verify compatibility with current electronic ballasts and drivers. The device frees the installer from specifying separate controls for different lamp technologies.

Surge Protection and Fail Behaviour

Enhanced surge protection uses 255J and 510J MOV components to absorb transients. The photocell switches on at 1.5 foot-candles with a 1.5 : 1 off/on ratio. Fail mode defaults to on, keeping the circuit energised if the sensor fails. The unit meets or exceeds ANSI C 136.10 / C 136.24 and UL/CSA requirements for safety and durability.

Questions about this item

How long will the electronic photocontrol last before the relay wears out under daily dusk-to-dawn cycling?

The unit is designed and tested for a 10 to 20 year service life expectancy with full on/off lifecycle testing under tungsten, magnetic and electronic ballast loads.

What surge energy can the 255 J and 510 J MOV components absorb during continuous outdoor operation?

Enhanced surge protection uses 255 J and 510 J MOV components that meet or exceed ANSI C136.10 / C136.24 and UL/CSA requirements for lightning and transient events.

Which voltage supply and wiring must already be in place for the stem-mount sensor to operate?

The control requires a 105–305 VAC supply and connects with 6-inch leads rated for 1000 W tungsten, 1800 VA magnetic ballast or 6 A electronic ballast loads.
