Product Overview

The Allen-Bradley 42KL-L2LB-F4 is a PHOTOSWITCH MiniSight visible red fiber optic photoelectric sensor manufactured by Rockwell Automation. It is part of the Bulletin 42KL sensor family and is designed for operation with compatible plastic fiber-optic cables. The sensor uses a 660nm visible red LED and a small-aperture fiber-optic sensing configuration. It operates from a manufacturer-specified 10.8–30V DC supply, with 35mA supply current and NPN/PNP output rated for a maximum load current of 100mA. The standard-speed 42KL-L2LB-F4 provides a 1ms response time with selectable Light Operate / Dark Operate modes. Adjustable sensitivity enables the detection threshold to be configured according to the selected fiber-optic arrangement and the application requirements. The sensor is equipped with a 4-pin DC Micro quick-disconnect interface on a 152mm (6in) pigtail. The exact sensing distance and field of view depend on the compatible fiber-optic cable selected for the application; no universal fixed sensing range should be assumed. The MiniSight family features a compact rectangular housing with an 18mm mounting nose, status indicators for power, output and operating margin, and manufacturer-specified protection against short circuits, reverse polarity and false pulses. Rockwell Automation lists the enclosure protection as NEMA 4X / 6P / IP67 when installed under the appropriate environmental and connection conditions. The manufacturer-specified operating temperature range is -20°C to +70°C. Rockwell Automation currently lists the exact catalog number 42KL-L2LB-F4 as Active. The supplied actual packaging photograph identifies 42KL-L2LB-F4, Series B, with date marking 2026/04/08 and PRODUCT OF DOMINICAN REP.. The package also identifies an 11–30V DC input range, NPN/PNP output and 100mA maximum load. The physical sensor nameplate, actual 4-pin connector, supplied fiber-optic cable and functional condition have not been independently verified. Please confirm the correct fiber-optic cable, electrical interface and supplied accessories before ordering.
