Industrial Inductive Sensor M18 8mm
The Turck NI8-S18-AZ3X/CSA 4350500 is a flush-mount inductive proximity sensor built for industrial automation and machine monitoring. Its M18 × 1 threaded barrel allows direct installation into standard mounting points on conveyors, presses, or assembly fixtures. The sensor detects ferrous targets at a rated switching distance of 8 mm without physical contact. It suits maintenance engineers and OEM integrators who need reliable presence detection in harsh environments.
AC/DC Two-Wire Operation Limits
This unit operates on both AC and DC supplies with a two-wire NO contact output, rated for 20250 VAC and 10300 VDC switching voltage. The two-wire design simplifies wiring but introduces a residual current and voltage drop that must be compatible with the connected PLC input module. Cable connection is fixed, so cable routing and strain relief must be planned during installation. The PA12-GF30 housing resists oils, coolants, and mechanical impact but is not rated for continuous high-temperature exposure beyond the material limits.
Upgrade From Mechanical Limit Switches
The sensor replaces mechanical limit switches and older inductive models with shorter sensing ranges or non-flush mounting requirements. The jump is worth it when contact bounce, wear, or actuator alignment cause downtime on high-cycle lines. The 8 mm flush range allows the sensor face to sit level with surrounding metal, protecting it from glancing blows. Buyers who need longer range, non-flush mounting, or complementary PNP/NPN output types should verify specifications before ordering.

Questions about this item
Should I choose the 8 mm switching distance version or a different range for my M18 threaded barrel sensor?
The NI8-S18-AZ3X/CSA provides an 8 mm rated switching distance with flush mounting on an M18 × 1 barrel, so select it when that exact sensing range matches your application.
What does the 8 mm rated switching distance mean when the sensor is installed in a machine?
It means the sensor will reliably detect a standard target at up to 8 mm from the sensing face when mounted flush in an M18 × 1 threaded hole, giving a consistent trigger point for position sensing.
How does the AC 2-wire 20-250 VAC and DC 2-wire 10-300 VDC interface limit what I can connect it to?
The two-wire design works directly across 20-250 VAC or 10-300 VDC supplies, so it can replace mechanical switches in those voltage ranges but cannot be used with low-voltage logic inputs that need a separate signal wire.
