Royce Thompson Electric V9032 Lighting Controller Detector, Cadmium Sulphide, Remote Mount, 220 to 270 V, 20 mm Diameter

Automatically manage your industrial light systems with this lighting controller from Royce Thompson Electric. It's a two-part component with a photocell detector and controller that turn the lights on and off depending on the time of day. The detector is housed in a robust polycarbonate casing that's resistant to impact, so you can use it in harsh conditions. As it consumes just 0.6W of power, this is an energy-efficient solution. You can set the switching requirements of this device to suit your design specifications.

• Compact controller dimensions of 57 (length) x 31 (width) x 25mm (height) for installation in setups with limited space

• Car park lighting systems

This lighting controller is self-extinguishing, so it will stop burning within a short time when a fire occurs. It's also flame-resistant and can help reduce the spread of fire.

Remote IP65 detector

These controllers automatically turn lights 'ON' and 'OFF' in response to changes in ambient light levels, primarily the transition from day to night and vice-versa. The more advanced types (see note below) have inbuilt logic to minimise false triggering, whereas the remainder have inbuilt time delays or higher 'OFF' thresholds, to prevent on/off cycling. As a general rule, these controllers should be sited such that they are not illuminated, by the light they are controlling. Nominal supply voltage is 230Vac.,Note regarding energy-saving negative-hysteresis controllers,Where figures for the 'OFF' threshold are lower than for the 'ON' threshold, the sensor is designed such that four thresholds are actually monitored. These are: dusk, the middle of the night, dawn and the middle of the day. Monitoring at times other than dusk and dawn enables the sensor to determine what it should be looking for next, minimising false triggering and improving overall controller operation.
