Passive infrared sensor model TDL2025, color White Description A compact passive infrared motion sensor designed for DC powered lighting and control circuits. The sensor detects human movement within a wide cone, uses an integrated light sensor to avoid false activation in bright conditions, and outputs the same voltage as the input for straightforward compatibility with DC loads. Key benefits Reliable automatic switching: detects motion within a 110 degree cone and triggers continuous output while movement is present. Broad compatibility: works with DC supply voltages from 5 V to 24 V and outputs the same voltage as the input, making it simple to pair with common DC drivers and industrial power supplies. Low standby drain: static power consumption is only 50 uA, minimizing idle current draw. Adjustable timing: delay defaults to 18 seconds but can be set anywhere from 3 seconds to 350 seconds to match different application needs. Daylight awareness: builtin light sensor prevents activation above the preset ambient light threshold, reducing unnecessary switching. Compact form factor: 36 x 36 x 27 mm housing fits into tight spaces and standard junction boxes. Specifications Model: TDL2025 Type: Passive infrared sensor 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 3 to 350 seconds Light sensor: yes Sensitivity: default 3 lux to 6 lux Detection range: 110 degree cone angle, 3 m to 5 m Trigger mode: continuous trigger Size: 36 x 36 x 27 mm Compatibility and installation notes Designed to be placed inline between a DC power source and the load. Because output follows input voltage, no additional level conversion is required. Small footprint allows mounting inside compact enclosures, under cabinets, or within lighting fixtures where space is limited. Default sensitivity and delay settings can be adjusted on installation to match the specific lighting or control requirements of the site. Typical applications Corridor and stairwell lighting control where automatic, momentary activation is required and space for electronics is limited. Undercabinet or display lighting that should only turn on when a person is present and ambient light is low. Industrial and commercial DC lighting circuits where a compact motion detector is needed to work with existing 5 V to 24 V power supplies and drivers. This sensor provides straightforward motion detection, adjustable timing and light gating, and compact sizing for easy integration into a variety of DC lighting and control systems.
