Photo-Electric Sensors

The most common method of giving a start signal is with the use of a photoelectric product sensor. Alternatives to using a photoelectric sensor can be using a PLC, relay, or a mechanical switch. Any of these methods are well suited to trigger the LSI labeler.

Different types of sensors can be used to detect the product. The product size, shape, and color should all be taken into consideration when selecting a product sensor. Physical limitations for mounting the sensor must also be considered.
