XSZ INDUSTRIAL SENSORS
SZ-M74-M30DN Detection-Hole Sensor
A 74 x 48 x 15 detection-hole sensor series with a 30 mm detection-hole diameter and 4 mm minimum detection target.
30 mm detection-hole overview
This page contains only the 74 x 48 x 15 sensor with a 30 mm detection-hole diameter. The source lists a 4 mm minimum detection target for this selection.
The 30 mm model matrix includes NPN, PNP, DC, and AC variants in normally open and normally closed output logic. Confirm cable, wiring, target material, and installation clearance with XSZ before order.

Key product advantages
30 mm hole selection
The source-selected detection-hole diameter is 30 mm, with a listed 4 mm minimum detection target.
Output selection
The 30 mm column provides NPN, PNP, DC, and AC output configurations in NO and NC logic.
Side adjustment
The common specification lists side potentiometer sensitivity adjustment.
