Ultrasonic proximity switch with

Ultrasonic Sensors

Product Description

The sks sensor offers a non-contact

measurement of the distance to an

object which must be positioned

within the sensor’s detection zone.

Depending on the set window limits,

a distance-proportional analogue sig-

nal is output.

Via the push-button, the detect dis-

tance and operating mode can be

adjusted (teach-in). Two LEDs indi-

cate operation and the state of the

output.

Safety Notes

■ Read the operating instructions

prior to start-up.

■ Connection, installation and

adjustment works may only be

carried out by expert personnel.

■ No safety component in

accordance with the EU Machine

Directive.

Proper Use

sks ultrasonic sensors are used for

non-contact detection of objects.

Installation

■ Mount the sensor at the installa-

tion site.

Maximum torque of screws:

0,5 Nm

■ Connect a connection cable to the

M8 device plug.

plug and colour coding of the

microsonic connection cable

Start-Up

■ Connect the power supply.

■ Carry out the adjustment in

accordance with the diagram.

Factory Setting

■ Rising analogue characteristic

curve between the blind zone and

the operating range.

Synchronization

If several sensors are mounted close

to another, they should be synchroni-

zed with each other. This is done by

an externally provided synchronisati-

on signal.

■ Apply a square-wave signal to the

sync-input with pulse width t

and

repetition rate t

(Fig. 3 and

technical data).

Any amount of sensors may be syn-

chronized with this external synchro-

nisation signal.

A high level on the sync-input will

deactivate the sensor.

Maintenance

microsonic sensors are maintenance-

free. In case of excess caked-on dirt

we recommend cleaning the white

sensor surface.

Notes

■ The sks sensor uses an internal

temperature sensing element to

compensate the temperature de-

pending speed of sound. In the

first 45 seconds after power on

every time the sks tests this tem-

perature compensation and after-

wards sets the analogue output

according to the compensated dis-

tance value.

■ The temperature compensation

automaticly adjusts to the actual

mounting conditions if the sensor

outputs current of 11 to 13 mA or

voltage of 4.4 to 5.6 V for at least

30 minutes after switching on

power supply.

■ The sks sensor has a blind zone,

within which distance measure-

ments are not possible.

■ In the normal operating mode, an il-

luminated yellow LED signals that the

object is within the adjusted win-

dow limits.

■ If the push-button is not pressed

for 30 seconds during the teach-in

setting, the settings made hitherto

are deleted.

■ The sensor can be reset to its fac-

tory setting (s. »Further settings«).
