DocumentDocumentOperating manual wms ultrasonic sensor wms-25/RT/HV/M18 wms-35/RT wms-130/RT wms-340/RT wms-600/RT Product Description The wms sensors require a connection to the customer´s own control and signal evaluation equipment. Safety Notes Read the operating manual prior to start-up. Connection, installation and ad- justments may only be carried out by qualified staff. No safety component in accordance with the EU Machine Directive, use in the area of personal and machine protection not permitted. The wms sensors indicate a blind zone, in which the distance cannot be measured. The operating range indicates 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. Objects 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 Î Mount the sensor at the place of fitting. Î Connect a connection cable to the M12 device plug. Î Connect the sensor to your own control and signal evaluation equipment 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« subsequently transmitts all echo signals received depending on the duration as 1-bit values (echo yes/no). 21 34 1 3 4 2 +UB UB Echo Transmitter colour brown blue black white Fig. 1: Pin assignment with view onto the sensor plug and colour code of the connection cable *B7293* MV-DO-074368-784561 M12x1 M18x1 M12x1 M12x1 M12x1 Ø47.5 M12x1 Ø65 Technical Data wms-25... 1 U 4 2 3 +UB Transmitter Echo UB 24 width A/F 5 68 95 Blind zone 30 mm Operating range 250 mm Maximum range 350 mm Transducer frequency 320 kHz Resolution, sampling range 0.35 mm Angle of beam spread see detection zone Reproducibility ±0.15 % 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 recognized. The requirement is an optimal alignment of the sensor and reflector. It is not possible to evaluate ultrasonic reflections outside this area. 0 cm Plate 5 cm 10 cm Round bar ø 10 mm 15 cm 20 cm 25 cm 30 cm 35 cm 10 cm 5 cm 0 cm 5 cm 10 cm 20 cm 10 cm 0 cm 10 cm 20 cm 0.8 m 0.4 m 0m 0.4 m 0.8 m 1.6 m 0.8 m 0m 0.8 m 1.6 m 2.4 m 1.2 m 0m 1.2 m 2.4 m wms-35... 36 width A/F M30x1.5 5 65 mm 350 mm 600 mm 400 kHz 0.18 mm see detection zone ±0.15 % 64 84 0 cm Plate 10 cm 20 cm Round bar ø 10 mm 30 cm 35 cm 40 cm 50 cm 60 cm wms-130... 36 width A/F M30x1.5 5 wms-340... 36 width A/F M30x1.5 5 200 mm 1,300 mm 2,000 mm 200 kHz 0.18 mm see detection zone ±0.15 % 64 84 0 m Plate 0.4 m 0.8 m Round bar ø 10 mm 1.2 m 1.3 m 1.6 m 2 m 350 mm 3,400 mm 5,000 mm 120 kHz 0.18 mm see detection zone ±0.15 % 82 102 19.5 33 0 m Plate 0.8 m 1.6 m Round bar ø 27 mm 2.4 m 3.2 m 3.4 m 4 m 4.8 m 5.6 m wms-600... 36 width A/F M30x1.5 5 800 mm 6,000 mm 8,000 mm 80 kHz 0.18 mm see detection zone ±0.15 % 85 105 22.5 36 0 m Plate 1.2 m 2.4 m Round bar ø 27 mm 3.6 m 4.8 m 6 m 7.2 m 8.4 m Accuracy Temperature drift 0.17%/K Temperature drift 0.17%/K Temperature drift 0.17%/K Operating voltage UB/Voltage ripple 10 to 30 V DC, reverse polarity protection/±10 % No-load current 30 mA 30 mA 30 mA Housing Brass sleeve, nickel-plated, plastic parts: PBT; Ultrasonic transducer: polyurethane foam, epoxy resin with glass content Class of protection to EN 6052 IP67 IP67 IP67 Type of connection 4-pin initiator plug, brass, nickel-plated Operating temperature 20 to +70 °C 20 to +70 °C 20 to +70 °C Storage temperature 40 to +85 °C 40 to +85 °C 40 to +85 °C Weight 80 g 200 g 200 g Signal input (Transmitter) Controlled by open collector (npn); IC 3 mA, UCE 30 V Recommended tramsmitted pulse length 25 µs 80 µs 150 µs Recommmended measuring cycle time 8 ms 12 ms 20 ms Signal output (Echo) Positive-switched (pnp), Imax = 10 mA, short-circuit-proof and reverse polarity protection Order No. wms-25/RT/HV/M18 wms-35/RT wms-130/RT Temperature drift 0.17%/K 30 mA IP67 20 to +70 °C 40 to +85 °C 260 g 300 µs 40 ms wms-340/RT Temperature drift 0.17%/K 30 mA IP67 20 to +70 °C 40 to +85 °C 320 g 350 µs 65 ms wms-600/RT microsonic GmbH / Phoenixseestraße 7 / 44263 Dortmund / Germany / T +49 231 975151-0 / F +49 231 975151-51 / E info@microsonic.de / W microsonic.de The content of this document is subject to technical changes.
