Technical description and application scope
Application and selection
Leuze HTU420B-1000.3/L6-M8, article 50150576, is an ultrasonic sensor. Selected exact-model data: operating range: 0.02–1 m; ultrasonic frequency: 220 kHz; supply voltage: 12–30 VDC.
For ultrasonic selection, the lower end of the operating range matters as much as the upper limit. Maximum range does not establish reliable detection for a target too close to the sensor. Evaluate target angle, sound-absorbing surfaces and adjacent ultrasonic sources. Validate level or accumulation tasks using the actual material.

Engineering integration
Use article number 50150576 together with the complete designation HTU420B-1000.3/L6-M8 when selecting a replacement, checking a quotation or requesting technical support. Compare the actual installation space, power supply and controller requirements before purchase. A matching housing or a similar model suffix does not prove interchangeability.
Before commissioning, define an acceptance test with representative operating conditions. Record the configuration, reference samples and controller response. Repeat the relevant test after mechanical adjustment, wiring changes or replacement. Safety devices require validation of the complete protective function by competent personnel; ordinary sensing devices must not be assigned an unverified protective function.
