Passive Infrared Sensor Controller TDL2025, Black Compact, reliable PIR sensor module designed for integration with DC controllers and industrial power supply systems. The TDL2025 detects human presence and provides a direct output equal to the input voltage, making it simple to add presencetriggered switching to lighting, control circuits, and automation equipment. Key benefits Automated presence detection for hands switching and control, reducing the need for manual operation. Wide input voltage range supports common DC control systems and industrial power supplies, making the module easy to integrate. Adjustable delay and builtin light sensing allow the sensor to operate only when needed, improving control flexibility. Small footprint allows installation in tight enclosures or control panels. What makes it stand out True plugandplay output: output voltage follows input voltage for straightforward wiring to loads and controllers. Low static power consumption preserves system standby performance. Adjustable delay range covers short and long hold times without external components. Builtin light sensor and configurable sensitivity provide automatic day night behavior. Key specifications Model: TDL2025 Type: Passive infrared sensor Color: Black Working voltage: DC 5 V to 24 V Output voltage: equals input voltage Maximum load current: 5 A Static power consumption: 50 uA Delay time: default 18 seconds, adjustable from 3 to 350 seconds Light sensor: yes Sensitivity: default setting 3 lux to 6 lux Detection range: 110 degree cone angle, 3 to 5 meters Trigger mode: continuous trigger Size: 36 x 36 x 27 mm Compatibility and performance Works with DC control circuits and industrial power supplies within the 5 V to 24 V range. Output directly drives loads or interfaces with relays, solid state switches, and controller inputs, provided the load current does not exceed 5 A. Sensitivity and delay adjustments let you tune detection distance and hold time to match application requirements. Typical applications Corridor and stairwell lighting control where presencebased switching is required to activate fixtures only while areas are occupied. Factory and machine area automation to trigger local lighting or control signals when personnel enter a defined zone. Control panels and equipment enclosures where a compact presence sensor is needed to activate circuits without additional wiring complexity. Installation notes Mount with a clear line of sight to the monitored area for detection performance. Avoid mounting near heat sources or moving machinery that could generate false triggers. Verify system wiring and load ratings before connecting to ensure the maximum 5 A load limit is not exceeded. Use the sensitivity and delay adjustments to tailor the sensor response to site conditions and operational needs. The TDL2025 provides a compact, easy to integrate PIR sensing solution for a variety of DC powered control and automation applications.
