XSZ PROXIMITY SENSORS
LJ18A3-8-Z/BX Non-shielded Proximity Sensor
An 8 mm non-shielded proximity sensor range for metal-target detection, with DC NPN, DC PNP, DC two-wire, and AC two-wire choices.
8 mm non-shielded sensing choices
The XSZ LJ18A3-8-Z/BX is the non-shielded DC NPN normally open configuration with a listed 8 mm +/-10% sensing distance. The non-shielded matrix also includes NPN and PNP NO, NC, and NO+NC options, plus DC two-wire and AC two-wire models.
The reference lists a 0-7 mm setting distance, an iron 30 x 30 x 1 mm standard detection target, and DC or AC response-frequency values. Confirm dimensions, cable, and wiring with XSZ before order.
Key product advantages
Non-shielded 8 mm sensing
The non-shielded series is listed with an 8 mm +/-10% sensing distance and a 0-7 mm setting distance.
Multiple output options
The matrix includes DC NPN, DC PNP, DC two-wire, and AC two-wire model codes for electrical selection.
Metal-target reference
The listed standard detection target is iron 30 x 30 x 1 mm; non-magnetic metals have a reduced sensing distance.

Where it helps
Selection and installation checklist
- Select NPN, PNP, DC two-wire, or AC two-wire output and the required NO, NC, or NO+NC operation.
- Use the listed 8 mm non-shielded sensing distance and 0-7 mm setting distance during installation planning.
- Match the target to the listed iron 30 x 30 x 1 mm standard detection target.
- Confirm dimensions, cable, connector, wiring, and target compatibility with XSZ before order.
