※Pin ①, ② are not used terminals.

※For DC 3-wire type connector cable, it is available to use with

black wire(12-24VDC) and blue wire(0V).

※Please fasten the cleat of connector not to shown the thread.

(0.39 to 0.49N.m)

※Please fasten the vibration part with Teflon tape.

※Refer to the G-6 about IEC standard connector wires and

specifications.

※②,③ of N.O. type and ③,④ of N.C. type are not used terminals.

※The pin arrangement of connector applying IEC standard is being

developed.

※Please attach "I" at the end of the name of standard type for

purchasing the IEC standard product. Ex)PRDWT12-4DO-I

※The connector cable for IEC standard is being developed. Please

attach "I' at the end of the name of standard type.

Ex)CID2-2-I, CLD2-5-I

When several proximity sensors are mounted close to one

another a malfunction of the sensor may be caused due

to mutual interference. Therefore, be sure to provide a

minimum distance between the two sensors as below chart

indicates.

When sensors are mounted on metallic panel, you must

prevent the sensors from being affected by any metallic

object except target. Therefore, be sure to provide a

minimum distance as below chart indicates.

Please make the current on proximity sensor smaller than

the return current of load by connecting a bleeder resistor in

parallel.

※W value of Bleeder resistor should be bigger for proper

heat dissipation.
