All models are standardly equipped with the following protection circuits in their compact bodies. These protection circuits minimize the possibility of sensor malfunctions caused by erroneous wiring.
①.Reverse supply polarity protection circuit
②.Reverse output polarity protection circuit
③.Output short-circuit protection circuit
*As of April 2017, in-company survey.
Our original integrated molding method has eliminated grooves and gaps on the sensing surface and main body, thus reducing the possibility of malfunctions caused by splashing water or dust.
The beam emitting and receiving sections are 0.5 mm 0.02 in thinner than those on our conventional models while their external dimensions are the same. As a result, the distance between the beam emitting point and receiving point increased by 1 mm 0.039 in. The wider distance means less possibility of collision between the sensing section and sensing object.
The upper-limit and lower-limit positions of beam can be visually confirmed from the front, back, right and left sides of the sensor unit. This allows easy adjustment of the position of sensing object.
The large operation indicator (orange) lights up when the beam enters. The indicator is easy to see from above and from the sides.
The sensor unit can be installed with M2 or M3 screws.
(M2 screws, M3 screws and washers are not included.)
■Models requiring one M2 or M3 screw for installation : PM-F25, PM-R25
■Models requiring two M2 or M3 screws for installation : Models other than above
The sections where stress concentrates, such as the connecting section of the cable and internal circuit, are covered with a resin. This helps prevent malfunctions caused by vibrations and impacts.
