Panasonic EX13EB single-beam photoelectric sensor (through-beam), range 0.5 m, model EX13EB

Panasonic EX13EB single-beam through-beam photoelectric sensor from the EX10 series is designed for reliable short-range object detection. The sensor set includes separate transmitter and receiver units arranged opposite each other to detect presence or absence of objects within a 0.5 m sensing distance. This compact through-beam sensor suits confined spaces and simple automation tasks where stable, high-contrast detection is required.

Advantages

The through-beam arrangement provides stable detection of very small or low-reflectivity objects because the receiver responds directly to interruption of the beam. Compact housing enables installation in limited spaces and straightforward alignment. The sensor’s short 0.5 m range reduces interference from background objects and is suitable for focused detection on conveyors, chutes, or machine infeed points.

Suitable for

• Conveyor monitoring and small-part counting
• Detection of small or low-reflectivity components
• Access or position sensing in compact machinery
• Short-distance presence/absence detection in automation lines

Key specifications

• Sensing principle: through-beam (single-beam transmitter and receiver)
• Sensing range: 0.5 m
• Detection target: presence/absence of objects interrupting the beam
• Mounting: compact housing suitable for confined installation spaces
• Typical applications: conveyor monitoring, small-part detection, access sensing

How to use

Install the transmitter and receiver opposite each other so the optical axis is unobstructed across the intended sensing gap. Align the units to ensure the receiver receives the transmitter beam under no-object conditions, then secure mounting to prevent misalignment from vibration. Connect power and output wiring according to system requirements and verify detection by passing representative objects through the beam path. Adjust mounting positions to set the sensing zone precisely at the required location.

Recommendations

For reliable operation, keep the optical surfaces clean and free of dust or debris and avoid direct exposure to strong ambient light sources. Use mechanical guards or shields if there is a risk of physical damage. When integrating into control systems, allow for debounce or filtering in the logic to prevent false counts from brief beam interruptions.
