TDL2025 Passive Infrared Sensor Controller Module, White Key benefits Reliable motion detection for automated control: Detects human or object movement and provides a stable output that matches the input voltage for easy integration into controller circuits. Low standby power for energy efficiency: Very low static current reduces power draw when idle. Flexible timing and lightaware operation: Adjustable delay and integrated light sensor allow the module to activate only when needed and for a controlled duration. Main features Model: TDL2025 Type: Passive infrared sensor module for controller and industrial power supply applications Color: White Working voltage: DC 5 V to 24 V Output: Voltage equal to input voltage; maximum output current less than 5 A Static power consumption: 50 uA Delay time: Default 18 seconds; adjustable from 3 seconds to 350 seconds Light sensor: Included, allowing operation based on ambient light level Sensitivity: Default 3 lux to 6 lux Detection coverage: 110 degree cone angle, effective range 3 m to 5 m Trigger mode: Continuous trigger Size: 36 x 36 x 27 mm Why customers need this module Simplifies integration with existing DC control systems because output follows the input voltage and supports a wide input range. Reduces unnecessary activations by combining motion detection with a light sensor and adjustable sensitivity and delay settings. Conserves energy with very low static consumption while remaining ready to trigger when motion is detected. Compatibility and performance notes Designed to interface with controllers and industrial power supplies that accept DC 5 V to 24 V inputs and require a motiontriggered output. Output current capability is suitable for driving relays, LED drivers, or control inputs that draw less than 5 A. Compact footprint at 36 x 36 x 27 mm for installation in confined control panels or modules. Practical applications Corridor or stairway lighting control: Automatically switch lights on when motion is detected and ambient light is below the sensitivity threshold, with adjustable hold time to avoid frequent on/off cycling. Access control and alarm systems: Serve as a motion input to controllers for doors, gates, or alarm logic, providing continuous trigger capability within the 110 degree detection cone. Industrial automation: Integrate into machine or conveyor controls to start or stop processes when personnel enter a defined area, while keeping power consumption minimal. What makes it stand out Wide input voltage range and an output that mirrors the input voltage simplify wiring and compatibility with many DC control systems. Combination of motion detection, light sensing, and adjustable timing provides flexible behavior without extra components. Small size and low idle current make it practical for compact and energysensitive control applications. Installation tips Mount with a clear line of sight for the target detection zone and orient to cover the intended 110 degree cone. Adjust sensitivity and delay based on ambient lighting and required response time to minimize false triggers. Verify the connected load does not exceed the module output current capability of less than 5 A.
