lectrical connection

A sensor with NPN or PNP output can be loaded only by resistive

or inductive load. The positive pole of the supply voltage (+U) is

connected to the brown wire BN or pin connector no.1, the neg-

ative pole (0 V) is connected to the blue wire BU or pin connector

no. 3 and load on the black wire BK or pin connector no. 4. The

capacitative loads and low resistance loads (bulb) are evaluated

by the sensor as a short circuit.

Wiring diagrams are provided in the figures on the right.

Note: In case of strong ambient electromagnetic interference,

paralleling of conductors with power distribution, or for the distri-

bution to distance over 30 m, we recommend using shielded cable.

Sensors RFLS-35 with type of cable outlet A, B, V or H are

connected to assessing units permanently connected by PVC

cable. Design diagrams are provided on page 3.

Sensors RFLS-35 with connection method type C (see page

3) are connected to assessing units by means of a connector

socket with compression cable (length 2 or 5 m), or by means of

a connector socket without cable (see accessories). In this case

the cable is connected to the inside pins of the socket according

to the figure on the right. The recommended diameter of this

cable is 4 to 6 mm (the recommended cross-sectional area is

0.5 to 0.75 mm

ensor settings

Settings are performed by placing the magnetic pen on the sensitive

spot marked "+" or "–" located beside the connector or cable gland.

This method is used to set the sensitivity to the measured medium,

switching (O, C), with or without the presence of medium. The third func-

tion is designed for fine-tuning the sensor sensitivity. Upon a change

in the measured medium, it is necessary to perform new limit settings.

Information on settings of the sensor are stated in the instructions for use.
