XSZ PROXIMITY SENSORS
SZ-M18-5DN M18 Flush Proximity Sensor
An M18 flush proximity-sensor range with 5 mm, 8 mm, and 12 mm sensing-distance selections for compact industrial detection points.
M18 flush sensing for defined machine positions
The XSZ SZ-M18-5DN is the 5 mm M18 flush DC NPN normally open model shown in the supplied reference. The same flush series also lists 8 mm and 12 mm variants with selected NPN, PNP, and AC two-wire output options.
The product image specifies an 18 mm diameter and shows 52 mm / 60 mm body-length references. Confirm the exact body length and electrical configuration for the selected model with XSZ before order.
Key product advantages
Flush M18 construction
All model variants shown in this page use the supplied M18 flush installation type and an 18 mm diameter reference.
Three flush ranges
Select the source-listed 5 mm, 8 mm, or 12 mm flush sensing distance according to the required detection layout.
Output selection
The table maps the source-listed DC NPN, DC PNP, DC two-wire, and AC two-wire model codes for the flush series.

Where it helps
Selection and installation checklist
- Select only a flush model from the 5 mm, 8 mm, or 12 mm columns shown above.
- Match the selected sensing range to the required target clearance and use the corresponding standard target as a reference.
- Confirm the exact body length, supply voltage, consumption-current type, output-load type, and wiring before order.
- Validate sensing performance with the actual target, especially when using a non-magnetic metal.
