Accessories:

(available separately)

 Carriage short (Part No. 50114055)

As replacement for the series part.

 Extended carriage (Part No. 50114056)

For better guiding of oversized labels.

Remarks

Intended use:

The ultrasonic label forks are
ultrasonic sensors for con­tactless detection of the gap
between two consecutive
labels on a carrier tape.

Operate in accordance with
intended use!

 This product is not a safety sensor

and is not intended as personnel
protection.

 The product may only be put into

operation by competent persons.

 Only use the product in accor-

dance with the intended use.

 To achieve high repeat-

ability, the label tape must
be slightly under tension.

 Align the label tape

according to the sensor's
marker "Label center posi­tion" (see also marking on
sensor).

 The label material used

determines the achievable
precision and the reliability
of gap detection!

 Light switching: signal in

the label gap.

 Dark switching: signal on

the label.
