XSZ INDUSTRIAL SENSORS
SZ-M74-M20DN Detection-Hole Sensor
A 74 x 48 x 15 detection-hole sensor for the source-listed 20 mm hole configuration.
20 mm detection hole
2 mm minimum target
Focused 20 mm selection
This page is arranged around one source-supported version only: the 74 x 48 x 15 housing with a 20 mm detection-hole diameter and 2 mm minimum detection target.
Use the fixed model matrix below to select the required NPN, PNP, DC, or AC code and normally open or normally closed output logic. Confirm cable, wiring, target material, and installation clearance with XSZ before order.
Model selection
Select the electrical type and output logic; each repeated electrical type is grouped for faster comparison.

Dedicated size data
Only the 20 mm hole configuration is shown, avoiding mixed size comparisons.
Clear output mapping
The table maps every listed NO and NC code without changing the source model numbers.
Practical adjustment
The supplied parameters list side potentiometer sensitivity adjustment and IP67 protection.
