871T-L5A18

The Allen Bradley 871T-L5A18 is classified as an inductive proximity sensor tailored for precision in non-contact detection applications. It is capable of operating within a supply voltage range of 10 to 30 Volts DC, making it suitable for different systems that require reliable sensing capabilities. The nominal sensing distance of this sensor reaches 5 millimeters (0.2 inches), allowing it to work effectively in close proximity environments.

Constructed with a plastic face and a shielded tubular threaded barrel, it features a robust design meant to withstand various operational conditions. The barrel diameter measures 18 millimeters (0.7 inches), and the housing is fabricated from stainless steel, which contributes to its durability and resistance to harsh conditions.

The sensor exhibits a voltage drop of less than 1 Volt, ensuring efficient performance, while the output configuration is designed as Normally Open (NO), following the Positive-Negative-Positive arrangement. A noteworthy switching frequency of up to 1,000 Hertz further enhances its capability, allowing it to respond rapidly to changes in the detected environment.

Wiring is simplified with a 3-wire configuration, and it includes a 4-pin mini style quick-disconnect connector for easy integration. Additionally, the sensor maintains leakage current levels below 10 microamperes and supports a load current of less than 400 milliamperes, ensuring safe operation. Designed for a wide operational temperature range from -40°C to 70°C (-40°F to 158°F), the 871T-L5A18 is suitable for diverse applications across various industries.
