XSZ PROXIMITY SENSORS
LJC30A3-H-Z/BX M30 Non-shielded Proximity Sensor
An M30 non-shielded proximity sensor range for dielectric-material detection, with DC NPN, DC PNP, and AC two-wire choices.
M30 non-shielded sensing choices
The XSZ LJC30A3-H-Z/BX is the M30 non-shielded DC NPN normally open configuration with a listed 20 mm +/-10% sensing distance. The filled non-shielded matrix also includes NPN NC, PNP NO, PNP NC, AC two-wire NO, and AC two-wire NC models.
The drawing marks M30 x 1.5, 70 mm and 60 mm length references, a 10 mm sensing-end reference, two clamp nuts, two buckle washers, and a red action display light. Confirm cable and wiring with XSZ before order.
