XSZ PROXIMITY SENSORS
SZC-M8-1DN M8 Shielded Proximity Sensor
A compact DC sensor for close-range presence and position checks in space-constrained industrial equipment.
M8 shielded sensing for compact machine positions
The XSZ SZC-M8-1DN is the M8 shielded, NPN normally open model in the supplied M8 matrix. Its 1 mm +/-10% sensing distance and 0-0.8 mm setting distance support close-range applications where mechanical clearance is limited.
The source product drawing shows an 8 mm body diameter and 45 mm body length. Select this version when its NPN normally open switching logic matches the connected controller.

Key product advantages
Compact M8 sensor body
The supplied drawing lists an 8 mm body diameter and 45 mm body length for the shielded M8 construction.
NPN normally open output
The SZC-M8-1DN is listed as a DC NPN normally open model. Confirm the wiring and input compatibility before order.
Shielded close-range sensing
The listed shielded configuration provides a 1 mm +/-10% sensing distance with a 100 Hz response frequency.

Where it helps
Selection and installation checklist
- Verify that NPN normally open logic matches the connected DC controller input.
- Use the shielded M8 model where the 1 mm +/-10% sensing distance and 0-0.8 mm setting distance suit the application.
- Confirm the actual target material and required sensing behavior with XSZ before order.
- Confirm supply voltage, wiring, housing material, environmental conditions, and cable specification before final selection.
- Choose the non-shielded M8 variant only if its separate 2 mm +/-10% sensing distance fits the installation.
