18 mm inductive proximity sensor
The Telemecanique Sensors XS618B1MAL2 is an 18 mm cylindrical inductive proximity sensor designed for industrial automation and machinery applications. It detects metal targets without physical contact using a shielded sensing face. The unit operates on a wide 24 to 240V AC/DC supply and provides a normally open two-wire output. Its nickel-plated brass housing carries NEMA 4X, IP68 and IP69K ratings for harsh environments.
Sensing range and wiring constraints
The sensor offers a maximum detecting distance of 8 mm, which limits it to close-range presence detection. Operating frequency is rated at 25 Hz on AC and 1000 Hz on DC, setting the practical speed limit for repetitive triggering. A fixed two-metre cable provides the electrical connection; there is no quick-disconnect plug, so cable routing and strain relief must be planned during installation. The 200 mA maximum current load restricts the sensor to driving small control loads directly.
Shielded 18 mm format with 8 mm range
The shielded 18 mm barrel with an 8 mm sensing range is the specification that determines fit. It allows flush mounting in metal brackets while maintaining the stated detection distance. Buyers who need a longer sensing range, an unshielded barrel for non-flush mounting, a PNP or NPN three-wire output, or a connectorised cable should select a different model.

Questions about this item
Should I choose the 8 mm detecting distance or a different range for this 18 mm sensor?
This model provides an 8 mm maximum detecting distance; the sensor is shielded and fixed at that range, so no alternative distance is offered for the XS618B1MAL2.
What does the 24 to 240 V AC/DC power requirement mean when the sensor is installed in a machine?
The sensor operates directly on any supply between 24 V and 240 V AC or DC, drawing up to 200 mA load current without a separate power supply.
How does the 2-wire output interface limit the switching frequency in practice?
The 2-wire NO output switches at up to 25 Hz on AC and 1 000 Hz on DC, so the AC line frequency caps the practical speed on alternating current.
