characteristic

Ultra small and space saving

Ultra small specifications help to miniaturize the device and save space.

超小型、节省空间

The equipment has two independent outputs

All models are equipped with two independent outputs - ON for incoming light and ON for shading, which can meet different output requirements depending on the usage location.
Due to the fact that the equipment has two independent outputs, there is no tedious operation of using input control lines to control the output mode, and there is no need to worry about accidents caused by opposite actions due to wire breakage. Just connect the wires corresponding to the desired output mode.

装备有两个独立的输出

Attention: For unused output lines, please make sure to perform insulation treatment.

Multiple models to choose from

There are 5 shapes and 15 models available.
You can choose the model that meets your installation requirements.

Global applicability

Compliant with European EMC specifications. And obtained UL certification.
PM - □ 24 has also obtained certification for the Korean S logo.
PNP output type is also available. Can be used with confidence on export machines.

(Note 1): When not specified, the measurement condition is an ambient temperature of+23 ℃.
(Note 2): The reaction frequency refers to the numerical value when the disk in the figure rotates.

(Note 3): If used in an environment temperature above+50 ℃, be sure to install the sensor on a metal body.
(Note 4): Please note that when the ambient temperature is below -10 ℃, PM - □ 24-R cables will lose their stretchability.
(Note 5): PM - □ 24-R cable is suitable for bending resistant cables on mobile machine bases. When the sensor is installed on the mobile machine base, fix the sensor cable contact so that no pressure is applied on it.
(PM - □ 24-R is not suitable for installation on mobile machine bases.)
