Product Description
Compact Size Picking Sensor NA1-PK3
Photoelectric Sensors are a type of sensor that uses light to detect the presence or absence of an object. They offer a wide variety of type to choose from.
[Feature]
● Shape : block same size as pocket lighter
● Detection Distance (mm.) : 30 to 300
● Sensing modes : Through Beam Type
● Output Mode : NPN and PNP
[Application]
Photoelectric Sensors are commonly used in industrial applications for example conveyor belts, assembly lines and so on

Features
- Make sure to use safety light curtains when using a sensing device for personnel protection.
Space-saving, pocket lighter-sized unit
Ultra compact size: W24 x H70 x D8 mm W0.945 x H2.756 x D0.315 in. |  |
Utilizes a large, bright, clearly visible job indicator
The ultra compact body incorporates a job indicator approx. 50 mm 1.969 in tall.
Due to its brightness and high visibility, it is now possible to check sensor operation even from a distance.

No synchronization wires required
Synchronization wires are not required, due to the utilization of a synchronized scanning system that results in a reduction of wiring man-hours. In addition, the sensors can be switched among three different emission frequencies, allowing up to three sets of sensors to be installed closely together in the same vertical plane, without causing mutual interference. Even when installed in multistage shelving, malfunctions due to mutual interference will not occur. (When mounted horizontally, a maximum of two sensor sets may be used side-by-side, without interference.) |  |
Switchable output operation
Output operation can be switched to suit the desired application.
Sensor protection brackets are available
Sensor protection brackets are now available (optional), to protect sensors from damage due to tools and other objects. The protection brackets have a black coating, which enhances the visual effectiveness of the job indicator. |  |
Easy alignment
The sensor's beam axis is directly in line with the mounting holes, making sensor alignment easier. |  |
Flexible cable orientation
The cabling can be oriented in either of the two different directions: downward or sideways, thus permitting a flexible layout, in accordance with the sensor's mounting position. |  |
