Leuze LE5B/4X-200-M8 Throughbeam photoelectric sensor receiver

The LE5B/4X-200-M8 is a throughbeam photoelectric sensor receiver from Leuze that pairs with a corresponding emitter to detect interruption of a light beam. It provides a robust M8 connection and is designed for industrial machinery environments, with typical DC supply compatibility, a configurable output suitable for NPN/PNP logic, and mounting flexibility for compact installations. The device supports standard installation and wiring practices for throughbeam sensing in production lines, conveyors, and safety-related sensing points, with IP-rated housing suitable for workshops and factory floors. Description The Leuze LE5B/4X-200-M8 Throughbeam photoelectric sensor receiver accepts a light beam from a corresponding emitter and outputs a signal when the beam is broken or blocked. It is configured for reliable operation in industrial environments with a compact M8 connector footprint and straightforward mounting options. Electrical characteristics typically include a DC supply range suitable for 24V systems, low quiescent current, and an output configuration compatible with common PLC inputs (PNP or NPN variants). The device is designed for high-contrast detection across typical manufacturing distances up to the specified range (200 mm in the model, with throughbeam pairing). It supports standard mounting methods, including front- or side-mounting, with compatible brackets and adjustable sensing distance settings, and adheres to common industrial standards for photoelectric sensors. Use cases include machine guarding, part presence/absence detection, and process control where a separate emitter-receiver pair is advantageous. The receiver is designed to be used with the Leuze LE5B emitter in a throughbeam configuration and is compatible with standard sensor cabling and 4-wire or DC wiring practices, depending on the exact output configuration.
