No name TS-02B7 twilight sensor (dusk/dawn light switch) model TS-02B7

No name TS-02B7 twilight sensor is a compact dusk-to-dawn light switch that automatically controls lighting according to ambient light levels. The sensor detects changes in natural light and closes or opens the connected circuit to turn lights on at dusk and off at dawn. Designed for outdoor and semi-outdoor installations, the TS-02B7 is intended for reliable, hands-off operation of street lamps, garden lights, signage illumination and other lighting that requires automatic day/night switching.

Advantages

The TS-02B7 offers straightforward automatic control without the need for timers or manual switching. Its light-sensitive element responds to gradual changes in illumination, enabling smooth transition between on and off states. The device is compact and designed for simple integration into existing lighting circuits. Built for continuous operation, it reduces energy consumption by ensuring lights operate only during low-light periods.

Suitable for

• Street and pathway lighting
• Garden and landscape illumination
• Outdoor advertising and signage
• Porch, entrance and security lighting

Key specifications

• Operating principle: photoelectric dusk-to-dawn switching
• Sensing: ambient light level detection
• Mounting: wall or pole mounting in sheltered position
• Connection: wired input/output for integration with lighting circuits
• Typical environment: outdoor and semi-outdoor applications (protected from direct water ingress)
• Function: automatic on at low light, automatic off at sufficient daylight

How to use

Mount the TS-02B7 in a location where it can accurately sense ambient light without obstruction from artificial lights or heavy shading. Connect the sensor in series with the lighting circuit following safe electrical practices and local wiring regulations. After installation the device operates automatically: when ambient light falls below its sensing threshold the sensor closes the circuit to switch lighting on, and when light rises above the threshold it opens the circuit to switch lighting off. Periodic visual checks of mounting and wiring are recommended.

Usage recommendations

For reliable operation, install the sensor away from nearby light sources that could cause false triggering and position it where it remains protected from direct rain or spray. Verify that the chosen mounting height and orientation provide representative ambient light measurement for the controlled lighting area.
