Brand: Microsonic

Model: wms-25-RT-HV-M18

Type: User manual

Microsonic wms-25-RT-HV-M18 is an ultrasonic sensor designed for non-contact detection of objects. It features a blind zone of 5 cm and an operating range of up to 0.8 m for round bar ø 10 mm objects. With a transducer frequency of 80 kHz and a resolution of 0.18 mm, the sensor offers precise and reliable measurements. It is equipped with an M18x1 connector and an IP67-rated housing, making it suitable for use in harsh industrial environments.

detection zones

for different objects:

The dark grey areas represent the

zone where it is easy to recognise

the normal reﬂector (round bar).

This indicates the typical operating

range of the sensors. The light

grey areas represent the zone

where a very large reﬂector – for

instance a plate – can still be reco-

gnized. The requirement is an

optimal alignment of the sensor

and reﬂector.

It is not possible to evaluate ultra-

sonic reﬂections outside this area.

Product Description

The wms sensors require a connection

to the customer´s own control and si-

gnal evaluation equipment.

Safety Notes

Read the operating manual prior

to start-up.

ԎConnection, installation and ad-

justments may only be carried

out by qualiﬁed staff.

No safety component in ac-

cordance with the EU Machine

Directive, use in the area of per-

sonal and machine protection

not permitted.

The wms sensors indicate a blind

zone, in which the distance cannot be

measured. The operating range indi-

cates the distance of the sensor that

can be applied with normal reﬂectors

with sufﬁcient function reserve. When

using good reﬂectors, such as a calm

water surface, the sensor can also be

used up to its maximum range. Ob-

jects that strongly absorb (e.g. plastic

foam) or diffusely reﬂect sound (e.g.

pebble stones) can also reduce the

deﬁned operating range.

Proper Use

wms ultrasonic sensors are used for

non-contact detection of objects.

Installation

Mount the sensor at the place of

ﬁtting.

ÎConnect a connection cable to the

M12 device plug.

Connect the sensor to your own

control and signal evaluation equip-

ment according to Fig. 1.

Signal input »Transmitter«

A signal on the input makes the wms

sensor emitting a sound pulse. For this

a open collector output has to earth

the »transmitter« signal input for the

time given in the technical data table

below.

Signal output »Echo«

The signal output »Echo« subsequent-

ly transmitts all echo signals received

depending on the duration as 1-bit

values (echo yes/no).
