XSZ PROXIMITY SENSORS
LJ12A3-2-Z/BX Shielded Proximity Sensor
A 2 mm shielded proximity sensor range for metal-target detection, with DC NPN, DC PNP, DC two-wire, and AC two-wire choices.
2 mm shielded sensing choices
The XSZ LJ12A3-2-Z/BX is the shielded DC NPN normally open configuration with a listed 2 mm +/-10% sensing distance. The 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 0-1.6 mm setting distance, an iron 12 x 12 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
Shielded 2 mm sensing
The shielded series is listed with a 2 mm +/-10% sensing distance and a 0-1.6 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 12 x 12 x 1 mm; non-magnetic metals have a reduced sensing distance.
