The design of Pantron photoeyes is crucial to their performance. Instead of placing the lens on the front of the photoeye, it is enclosed deep within the protective housing. This prevents the lens from becoming scratched or dirty. The piece on the front of the sensor that resembles a lens is actually a light filter. When the infrared beam is created, it is focused within the sensor and then passes through the external light filter. Using this method, the photoeye is capable of producing a beam that is extremely powerful. Pantron photoeyes are perfect for wet environments because they are 100% submersible and rated IP67.

All Pantron photoeyes, with the exception of the SlimLine series, may be used with any Pantron amplifier or multiplexer. Alignment may be performed easily using a length of string that should be stretched between the transmitter and receiver. Fine adjustments to the alignment should be made to the transmitter side to achieve the strongest beam.
