Panasonic EX13EAPN single-beam photoelectric sensor (through-beam) — range 0.5 m

Panasonic EX13EAPN is a single-beam through-beam photoelectric sensor engineered for short-range object detection. With a nominal sensing distance of 0.5 m, this compact unit provides a single light barrier channel for presence/absence detection, simple counting, and basic positioning tasks in automated systems and conveyor applications. The sensor's design focuses on reliable switching behavior and straightforward integration into machine and production line setups.

Advantages

The sensor offers a compact footprint and a focused detection range that simplifies installation in tight machine spaces. As a through-beam type, it provides stable detection even with dark or low-reflectivity objects and minimizes false triggers from ambient light. Electrical interfacing is simple thanks to a single output channel, which reduces wiring complexity for standard automation tasks.

Suitable for

• Object presence and absence detection on short conveyors
• Basic part counting and indexing in assembly lines
• Position sensing for small moving parts and fixtures
• Simplified safety interlocks and machine guards in low-risk environments

Key specifications

• Sensing principle: through-beam (single-beam)
• Sensing distance: 0.5 m (nominal)
• Output: single switching output (light barrier)
• Detection target: opaque and low-reflectivity objects suitable for through-beam sensing
• Form factor: compact sensor head designed for mounting in confined spaces

How to use

Install the emitter and receiver facing each other across the detection path with a clear line of sight and secure mounting to prevent misalignment. Connect the sensor to the control system following the manufacturer's wiring diagram for the single output channel and provide the specified supply voltage. Align the transmitter and receiver so the beam is centered on the target path, then test with representative workpieces to verify reliable switching at the rated 0.5 m distance. Adjust mounting or add mechanical guides if needed to ensure consistent object presentation through the beam.

Recommendations

For reliable operation, keep the optical surfaces clean and protected from dust, oil, and condensation. When detecting small or irregularly shaped parts, use mechanical guides or fixed jigs to maintain consistent presentation to the beam. Choose through-beam mounting to detect dark or transparent objects that may be challenging for diffuse sensors.
