Before foil packagingis closed up, a BOD 21M checks the individual compartments anddetects missing or extra items.Contour checkingOptical distance sensors continuously detect dimensions or contourson tongue and groove boards. Analog sensing detects individualdefects and gradual deviations directly for permanent monitoring ofthe production process.Photoelectric Distance SensorsSense any material or color,intelligent and flexible.Positioning with precision, ensuring maximum quality and efficientlycontrolling material flow means distance measurement using Balluffphotoelectric distance sensors. The versatile BOD 21M inits compact, rugged metal housing expands your applicationoptions in a product family including through-beam sensors,contrast and luminescence sensors.Wide-ranging functionality, the most modern sensor technologyand innovative manufacturing technology leave nothing to bedesired: For robotics and automation, assembly and handlingas well as packaging technology.– Variety of functions in a standard housing– Rugged metal construction– Adaptable installationSimply choose from among the variety of applications offered by theBOD 21M thanks to its output signal proportional to object distance.Color and material of the object are effectively ignored.Rapid startup and ease of operation with a rotary switch for teach-inmean added cost-effectiveness. And installation couldn‘t be easier.A variety of mounting brackets, dovetail clamps and a comprehen-sive mounting system means the BOD 21M can be convenientlyattached and oriented in any position.

Page 4:4Adaptive feedMultiple optical distance sensors measure components, assembledunits and packages on a conveying line. BOD 21M sensors evaluatethe outer dimension and contour so that these various parts can betransported to the next appropriate process steps. The rugged metalhousing guarantees long service life of the installation.Sag monitoringPrecise processing of films or sheet material requires that it be uni-formly conveyed. Tension-free material transport succeeds using theBOD 21M, which dynamically detects the height of the sag section.

The measuring rangeof 20...500 mm is freely selectable and can be set for yourapplication using the convenient rotary switch.Two independent switching outputs with push-pull final stageallow you to use the new BOD 21M as either PNP normallyopen or NPN normally closed. Using the switching points –easy to select using a rotary switch – you can employbackground suppression and reliable zone monitoring.Features– Measuring range selectable between 20 and 500 mm– Analog voltage or current signal– Two digital switching outputs, individually configurable– Central rotary switch for ease of setting– Rugged metal housing– M12 connector, rotatable 270°The measuring range and switching pointsare easily set using the rotary switch.[EmitterReceiverLED greenLED yellowrotatable270°
