Twilight switch AZ-112-LED with external probe, InRush relay 16 A (160 A/20 ms)

Intelligent lighting control with a dusk-to-dawn sensor AZ-112-LED

The AZ-112-LED dusk-to-dawn sensor is a reliable solution for automatically switching outdoor and indoor lighting on and off, depending on the light intensity. This provides comfort, energy savings and increased security. The device is particularly recommended for use with LED light sources, which are characterized by high energy efficiency but generate strong inrush currents during start-up. The sensor's design takes these specific LED properties into account, ensuring its long-lasting and trouble-free operation.

Functionality and application

This model of the sensor is designed for mounting on a DIN rail, which facilitates its installation in electrical distribution boards. Equipped with an external probe with a diameter of 10 mm, it allows for precise detection of changes in natural light intensity. The probe should be placed in a location providing constant access to daylight. Adjustment of the activation threshold (2-1000 lx) and hysteresis (approx. 15 lx) allows you to adapt the sensor's operation to individual needs and environmental conditions. The on delay (approx. 10 s) and off delay (approx. 20 s) minimize the risk of accidental switching caused by short-term disturbances, such as lightning.

Solid construction and technical parameters

The AZ-112-LED sensor has been designed with durability and reliability in mind. It has a relay with a resistance to inrush currents of up to 160 A / 20 ms, which guarantees safe operation even with loads generating high current pulses – typical for LEDs. The maximum AC-1 load current is 16 A at 230 V AC. The IP20 protection class provides protection against accidental contact, and the external probe has an IP65 protection class, which guarantees its resistance to weather conditions. The device occupies only one module (18 mm) on the DIN rail, which allows you to save space in the distribution board. The connection cables are screw terminals with a cross-section of up to 2.5 mm². The device's power consumption is only 0.56 W.
