Cylindrical 18 mm Photoelectric Sensor
The Telemecanique Sensors XU9M18MB230 is a retroreflective photoelectric sensor built for industrial automation and machinery control. Its cylindrical 18 mm housing fits standard mounting points on conveyors, packaging lines and material-handling equipment. The sensor operates on a wide 24 to 240V AC/DC supply, so it integrates directly into existing control cabinets without extra power supplies. It is suited for engineers and maintenance teams who need reliable object detection in a compact form factor.
Solid-State Relay Output with 2 m Cable
A built-in solid-state relay provides a bounce-free SPST switching signal for PLC inputs or contactor coils. The 2 m pre-wired cable eliminates field terminations and reduces installation time on the machine. Light-on operating mode means the output activates when the beam is reflected back, simplifying logic for presence detection. The cylindrical metal body resists vibration and coolant exposure common in machine-shop environments.
Upgrade from Mechanical Limit Switches
This sensor replaces mechanical limit switches that wear out, jam or require physical contact with the target. The 3 m sensing range allows non-contact detection of totes, pallets or parts at a safe distance, reducing maintenance downtime. The jump is worth it when repetitive actuation cycles cause switch failure or when the application demands a sealed, solid-state solution with no moving parts. Buyers who need longer range or background suppression should evaluate alternative sensing technologies.

Questions about this item
What does the 24-240V AC/DC supply range mean for wiring this sensor?
The unit accepts any voltage between 24 and 240 volts AC or DC, so it can connect directly to common industrial control voltages without an extra power supply.
Will the 18 mm cylindrical body fit through a standard M18 mounting hole?
Yes, the 18 mm diameter matches a standard M18 clearance hole, allowing direct through-panel mounting with a locknut.
How do I wire the 2 m cable for light-on operation, and what mistake should I avoid?
Connect the two-wire cable in series with the load; the solid-state relay closes when the beam is reflected. Do not apply voltage without a load or the output may be damaged.
