BUS006F, BALLUFF, ultrasonic sensor Q62K1, range 350–5 000 mm, 2× PNP

BUS Q62K1-PWX-35/340-S92K – ultrasonic sensor

Ultrasonic sensor BUS Q62K1-PWX-35/340-S92K uses the reflection of sound pulses for non-contact evaluation of an object or distance. The declared working range is 350–5 000 mm; below its lower limit, measurement reliability cannot be assumed. Unlike the optical principle, the colour of the object is not decisive, but ultrasonic measurement is affected by the shape, inclination and acoustic reflectivity of the target.

Technical specifications

What an ultrasonic sensor is and how it works

Ultrasonic sensor emits short sound pulses at a frequency above the limit of human hearing. It evaluates the distance or presence of the target from the delay of the reflection from the object. It does not require the object to be magnetic or metallic and, unlike optical sensors, is much less affected by the colour or transparency of the surface. It is therefore also used for plastics, packaging, bulk materials and, with suitable mounting, for level monitoring.

Where this model is used

• Monitoring material in a silo: distance from the sensor to the surface of bulk material or liquid.
• Machine automation: checking the distance of larger objects.
• Limit state: signalling that a set point has been reached using the switching output, if this variant has one.
• Machines with limited space: use of a right-angled body if it suits the mounting conditions.

How the measurement information gets into the PLC

2× PNP NO/NC contact is used to evaluate a set switching distance or window depending on the version. Verify PNP/NPN polarity, NO/NC logic and the number of outputs. A switching output alone does not provide a continuous analogue distance value.

How to choose and correctly use this variant

• Measuring range: 350–5 000 mm; observe the minimum distance and the upper limit of the range.
• Output: 2× PNP NO/NC contact.
• Connector / cable: Connectors, connector M12 × 1, 5-pole; choose compatible accessories.
