描述
XSZ PROXIMITY SENSORS
SZ-M18-8DN M18 Non-flush Proximity Sensor
An M18 non-flush proximity-sensor range with 8 mm, 16 mm, and 20 mm sensing-distance selections for industrial detection points that need an extended range.
M18 non-flush sensing for longer detection distances
The XSZ SZ-M18-8DN is the 8 mm M18 non-flush DC NPN normally open model shown in the supplied reference. The same non-flush series also lists 16 mm and 20 mm variants with selected NPN, PNP, and AC two-wire output options.
The product image specifies an 18 mm diameter and a 60 mm body-length reference for the non-flush M18 construction. Confirm the exact electrical configuration for the selected model with XSZ before order.
Key product advantages
Non-flush M18 construction
All model variants shown on this page use the supplied M18 non-flush installation type, 60 mm body-length reference, and 18 mm diameter.
Three non-flush ranges
Select the source-listed 8 mm, 16 mm, or 20 mm non-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 non-flush series.

Where it helps
Selection and installation checklist
- Select only a non-flush model from the 8 mm, 16 mm, or 20 mm columns shown above.
- Match the selected sensing range to the required target clearance and use the corresponding standard target as a reference.
- Confirm supply voltage, consumption-current type, output-load type, cable, and wiring before order.
- Validate sensing performance with the actual target, especially when using a non-magnetic metal.
