Panasonic EX13A single-beam photoelectric sensor (through-beam) — range 0.5 m, series EX10/EX13A

Panasonic EX13A is a single-beam through-beam photoelectric sensor from the EX10/EX13A series with a nominal sensing range of 0.5 m. The device uses separate transmitter and receiver units to detect interruption of the light beam, providing a compact solution for short-range object detection and presence monitoring in industrial and automation environments. The sensor is intended for applications where a clear line-of-sight detection over a short distance is required and where small footprint and reliable switching are important.

Advantages

The through-beam design delivers stable detection even for small, transparent or low-contrast objects because the receiver responds to direct beam interruption. Compact transmitter and receiver housings allow installation in tight spaces and on machinery with limited mounting room. The nominal 0.5 m sensing range supports precise positioning and short-distance detection tasks while minimizing false triggers from ambient light. The sensor is compatible with standard industrial mounting arrangements, enabling straightforward integration into conveyor, assembly and signaling systems.

Suitable for

• Short-range object detection on conveyors and chutes
• Presence sensing for assembly stations and pick-and-place equipment
• Detection of small or low-contrast parts where reflective sensors may fail
• Signal input for machine logic, counters and safety signaling where through-beam configuration is required

Key specifications

• Sensing principle: single-beam through-beam (separate transmitter and receiver)
• Nominal sensing range: 0.5 m
• Optical beam: direct line-of-sight infrared/visible light (manufacturer standard)
• Mounting: compact housings suitable for constrained spaces
• Typical output behavior: switching on beam interruption (compatible with standard industrial input circuits)

How to use

Install the transmitter and receiver facing each other with a clear unobstructed path and align them so the beam is centred on the receiver aperture. Secure both units using the recommended mounting points and adjust alignment until the receiver indicates a stable received signal. Connect the sensor outputs to the control system following safety and wiring standards for your equipment; verify the expected switching when the beam is interrupted by a test object at typical operating positions. Periodically inspect the optical surfaces for dust, debris or misalignment and perform re-alignment if detection becomes unreliable.

Recommendations

For reliable operation, protect the optical axes from direct strong ambient light and install mechanical guards if objects could strike the sensor housings. Use proper cable routing and strain relief to prevent connector damage and follow manufacturer specifications for supply voltage and input wiring. For applications requiring longer ranges or diffuse detection, consider appropriate alternative sensor types.
