Technical data
Type NI8-M18E-AP6X-H1141
ID 4611233
General data
Rated switching distance 8 mm
Mounting conditions Non-flush
Secured operating distance ≤ (0.81 × Sn) mm
Functional principle
Correction factors St37 = 1; Al = 0.3; stainless steel = 0.7; Ms
= 0.4 Inductive sensors detect metal objects
Repeat accuracy ≤ 2 % of full scale contactless and wear-free. For this, they use a

high-frequency electromagnetic AC field that
Temperature drift ≤ ±10 % interacts with the target. Inductive sensors
generate this field via an RLC circuit with a
Hysteresis 3…15 % ferrite coil.
