CNTD CJY-E economy cylindrical inductive proximity sensors detect metal targets without mechanical contact. The range combines nickel-plated brass housings, red operating indicators and IP67 protection, with nominal detection distances from 1mm to 15mm. Choose the sensing head and installation clearance first, then match the output circuit and supply voltage to the control input.
All models below use 10–30VDC. DNA is NPN normally open, DNB is NPN normally closed, DPA is PNP normally open and DPB is PNP normally closed. DNC and DPC provide complementary NO+NC outputs and require four conductors. Combined outputs are listed for the M12, M18 and M30 groups only.

Use 350Hz for the M18 5mm group. All listed AC two-wire models are 20Hz. Frequencies are average values measured with the standard target, spacing between successive targets equal to twice the target width, and a target-to-sensor gap of half the nominal sensing distance. Set the actual operating gap within the setting range.

These axial references follow the drawing endpoints and exclude the free cable. The attached drawings show the cable exit, indicator and mounting-nut geometry. The miniature 04E–6.5E groups have electrical specifications but no corresponding dimension drawings in this attachment.
Use the lettered geometry in the attached installation drawing: A is face-to-face spacing; B is parallel spacing; n is the required head exposure reference; Ød is the surrounding-metal opening diameter; ℓ and m are the axial / surrounding-metal references shown in the drawing. Values below are in millimeters and preserve the illustrated measurement endpoints.

For a single NPN/PNP output, brown connects to +V, blue to 0V and black is the output. Connect the load between +V and black for NPN, or between black and 0V for PNP. DC and AC two-wire sensors connect in series with the load; the diagrams allow the load in either lead. Use 90–250VAC for the listed AC models. The attachment retains circuit and NO/NC timing diagrams; the single-output diagrams do not define the fourth conductor of a NO+NC model.

Use these sensors for ordinary industrial metal-position detection within the specified target, gap, load and environmental conditions. Regional versions can differ. The manufacturer excludes personnel-safety functions, exceptionally high-reliability systems such as nuclear, gas and power infrastructure, severe outdoor or contaminated environments, fire or explosion hazards, strong acids or alkalis, and military or aerospace use unless specifically designed and confirmed for that application.
