PNP output type available Interference prevention Boasts a compact, pocket lighter size enabling universal installation Space-saving, pocket lighter-sized unit Utilizes a large, bright, clearly visible job indicator Ultra compact size: W24 × H70 × D8 mm W0.945 × H2.756 × D0.315 in. Can even be mounted within the small space constraints of parts containers. 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.

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-byside, without interference.) Output operation can be switched to suit the desired application. OPTIONS 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. MOUNTING Easy alignment Flexible cable orientation The sensor’s beam axis is directly in line with the mounting holes, making sensor alignment easier. Mounting can be performed simply by using M4 nuts. 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.

Orientation • The emitter and the receiver must face each other correctly. If they are set upside down, the sensor does not work. Correct Incorrect Cable Cable Cable Cable Interference prevention function • By setting different emission frequencies, three units of NA1-PK3 can be mounted close together, as shown in the figure on the below. Part description Emitter Job indicator (Orange) Receiver Job indicator (Orange) Sensor 1 Frequency mode switch Sensor 2 Operation/frequency mode switch Stable incident beam indicator (Green) Sensor 3 Operation indicator (Red) Power indicator (Green) • However, if the sensors are mounted close together as shown in the figure below, up to 2 sets of sensors are possible. Mounting Sensor 2 Sensor 1 • Use M4 screws with washers and M4 nuts. The tightening torque should be 0.5 N·m or less. (Purchase the screws and nuts separately.) M4 screws with washers Frequency setting M4 nuts Selection of operation • Set the both emitting and receiving frequency of Sensor 1 to FREQ. 1, the both emitting and receiving frequency of Sensor 2 to FREQ. 2 and the both emitting and receiving frequency of Sensor 3 to FREQ. 3. Make sure that the power supply is off while setting the selection switch. Emitter • The output operation can be selected by the operation/ frequency selection switch on the receiver.

However, in order to reduce noise, make the wiring as short as possible. • Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. • Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (single winding transformer) is used, this product or the power supply may get damaged. • In case a surge is generated in the used power supply, connect a surge absorber to the supply and absorb the surge. Others • Do not use during the initial transient time (0.5 sec.) after the power supply is switched on. • Take care that the sensor is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance. • Avoid dust, dirt, and steam. • Take care that the product does not come in direct contact with water, oil, grease or organic solvents, such as, thinner, etc. • To select the switch, a minus screwdriver is necessary. (Tip dimension: 2.5 × 0.6 mm 0.098 × 0.024 in) • These sensors are only for indoor use. DIMENSIONS (Unit: mm in) The CAD data can be downloaded from our website.
