This prevents the sensor from being affected by metallic objects other than the target. MUTUAL INTERFERENCE To prevent mutual interference between two sensors mounted opposite or parallel to each other, be sure to space the two sensors at a distance greater than that shown here.

However, the detection signal may be produced under either of the following two conditions. If a signal is produced from metal chips on the sensing head, remove the chips from the sensing head. Large Chips If the size (d) of the chips collected on the sensing head is greater than or equal to 2/3 of the size (D) of the sensing surface. d 2/3 x D d CONNECTION TO AC POWER SOURCE E2EZ-X4 0 18 mm (0.71 in) 0 16 mm (0.63 in) 27 mm (1.06 in) E2EZ-X8 0 30 mm (1.18 in) 0 32 mm (1.26 in) 45 mm (1.77 in) Model E2EZ-X41 E2EZ-X81 E2EZ-X4 5 mm (0.20 in) 40 mm (1.57 in) 5 mm (0.20 in) 16 mm (0.63 in) 54 mm (2.13 in) Sensing surface (D) 16 mm (0.63 in) 28 mm (1.10 in) Compressed Chips If chips are pressed against the sensing surface by an external force the sensor will detect the chips.
