⚡ Cylindrical Photoelectric Sensor

A cylindrical photoelectric sensor is a round‑body optical sensor (typically M12 or M18) used to detect the presence, absence, or position of objects without physical contact.
It uses light emission and reception to detect targets across short to long distances, depending on the sensing technology.

🔧 Key Features

• Cylindrical housing — Standard M12 / M18 threaded bodies for easy mounting.
• Multiple sensing modes — Diffuse, retro‑reflective, polarised, through‑beam, laser.
• Universal wiring — PNP/NPN, NO/NC, 2‑wire or 3‑wire.
• High immunity to ambient light — Reliable in bright or outdoor environments.
• IP65/IP67 protection — Dust‑tight and water‑resistant.
• LED status indicators — Quick alignment and diagnostics.
• M8/M12 connectors — Fast installation and replacement.

🧩 Telemecanique Cylindrical Photoelectric Families

• XUB — M18 cylindrical, the most widely used general‑purpose type.
• XUZ — Accessories (reflectors, brackets, mounting hardware).
• XU laser variants**** — For long-range or precise detection.

These are part of the broader Telemecanique XU photoelectric range.

🏭 Typical Applications

• Conveyor object detection — Presence, spacing, counting.
• Packaging machines — Carton detection, label sensing.
• Material handling — Pallet detection, flow control.
• Robotics — Part positioning, pick‑and‑place verification.
• Automated assembly — Component presence/orientation.

⭐ One‑line summary

A cylindrical photoelectric sensor is a compact M12/M18 optical detector used for universal, non‑contact object detection in industrial automation.
