Wide light band for reliable detection F eaturing a wide light band, the Leuze RK 46C.DXL VarOS retro reflective sensor is able to reliably detect both individual sensors. Other features include the ability to calibrate for detection of transparent, perforated or small objects as well as to reliably detect objects with depolarising media such as foil packaging.

cally represented by the company include Hengstler counters and encoders, EGE flow monitoring and specialised sen- sors, Pulsotronic inductive sensors, ABP drive components and Secatec magnetic switches. Contapulse controls also offers a com- plete technical advisory service for the most effective use of its products in automotive and other branches of engineering. q

small and large objects. Objects can be round, angular or both, with glossy sur- faces, have transparent shrink wrapped film or even be totally black, with gaps or with high ambient light levels. These Leuze sensors are ideal for when the objects to be detected or the associated environmental conditions deviate from the norm. The Leuze RK 46C.DXL VarOS retro reflective sensor is particularly effective in this regard as it responds to objects with the entire width of its light band, which gives it the capability to handle interruptions. The wide light band allows for detection over a 45 mm to 60 mm wide area. The sensitivity and/or resolution of the sensor can be adjusted easily by means of a button located on the rear housing. This Leuze sensor also features a handy ‘teach me’ function, which allows it to be adapted easily between two object sizes greater than 8.0 mm at the touch of a button. This ensures optimum flexibility of application. The use of this sensor does away with the need for expensive light barriers or multiple
