Three protection circuits standard on all models

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

Ample beam emitting / receiving distance of 6 mm 0.236 in

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.

Note : The above image is PM-K45.

Beam marks for easy adjustment

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.

Large and easy to see
Multi-angle operation indicator

The large operation indicator (orange) lights up when the beam enters. The indicator is easy to see from above and from the sides.

All models easy to mount with M3 screws

The sensor unit can be installed with one or two M3 screws.(M3 screws and washers are not included.)

• Models requiring one M3 screw for installation : PM-F65, PM-R65
• Models requiring two M3 screws for installation : Models other than above

Resistant to vibrations and impacts

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.
