The following safety precautions should be observed:

Use of Laser Product:

For the purpose of preventing any injury which may occur to the user by the use of the laser product in advance, the following standards have been established by the IEC Standards, EN Standards, JIS Standards, GB Standards, KS Standards.

• Never use this product as a sensing device for personnel protection.
• In case of using sensing devices for personnel protection, use products which meet standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.
• Avoid observing beams continuously, particularly in a dark surrounding environment.
• Do not look at beams using an optical device such as an optical telephoto system.
• Never attempt to disassemble, repair, or modify this product.
• Use of control or adjustment or performance of procedures other than those specified in this instruction manual may result in hazardous radiation expose.

Laser Hazardous Class:

This product belongs to “Class 2 laser product” according to IEC 60825-1:2014 (EN 60825-1:2014/A11:2021) “Radiation Safety of Laser Products”. A Class 2 laser emits visible light with the wavelength range of 400 nm to 700 nm under which eyes can be protected by an aversive reaction (Avoidance behavior) such as a blink. When an unexpected failure occurs, dangerous radiation may be generated. Therefore, pay special attention to safety.

The PANASONIC LS-H22 is a Long sensing range line reflective type sensor (Note: LS-H22 is the model No. for the long sensing range spot reflective type LS-H21 with the lens attachment for line reflective type LS-MR1). The specifications when used with the applicable amplifier LS-400 series are as follows:

The following cautions should be observed:

• This product has been developed / produced for industrial use only.
• This product has been designed to meet the specifications when it is used along with the optional exclusive amplifier. If an amplifier other than the exclusive amplifier is used, not only the specifications may not be met, but it may also be a cause for malfunction or break down. Hence, please ensure to use this product along with the optional exclusive amplifier.
• Always use the sensor with the connector to be joined to the amplifier.
• Make sure that the power is off while wiring to the amplifier.
• In case noise generating equipment (switching regulator, inverter motor etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
• If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
• Do not use the sensor during the initial transient time (0.5 sec.) just after the power supply is switched on.
• 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.
• Take care that the sensor head is not directly exposed to fluorescent lamp from a rapid-starter lamp or a high frequency lighting device, as it may affect the sensing performance.
• The sensor head cable cannot be extended.
• Make sure that stress is not applied to the sensor head cable joint.
• This sensor is suitable for indoor use only.
• Do not allow any water, oil fingerprints, etc., which may refract light, or dust, dirt, etc., which may block light, to stick to the emitting/receiving surfaces of the sensor head. In case they are present, wipe them with a clean, soft cloth or lens paper.
• Do not use the sensor in vaporous, dusty or corrosive gas atmospheres.
• Take care that the sensor does not come in contact with water, oil, grease or organic solvents, such as, thinner, etc.
• Make sure that the power is off while cleaning the emitting/receiving windows of the sensor head.

When mounting the PANASONIC LS-H22:

• The tightening torque should be 0.5N•m or less.
• When placing the sensor horizontally or vertically, the reflector must also be positioned horizontally or vertically.
• If the sensor is placed horizontally or vertically but the mirror is tilted, the reflection amount will decrease, which may cause unstable detection.

The diffuse reflective type (LS-H21 and LS-H22) incorporates the spot-size adjuster to adjust the size of spot diameter.

Turn the spot-size adjuster clockwise or counterclockwise to adjust the spot diameter at your desired detecting distance. However, if the adjuster is over turned, it may be damaged.

The lens attachment for line reflective type (LS-MR1) mounted in the long sensing range line reflective type (PANASONIC LS-H22) is removable.

• When LS-H22 is used without LS-MR1, it will provide the equivalent performance to the long sensing range spot reflective type (LS-H21).
• Keep the lens from dust, dirt, water, oil, grease, etc.
• Do not apply any excessive bending force to LS-MR1. Such force may cause damage.

To remove the LS-MR1 lens attachment:

[1] Insert a screwdriver into the fixing slot located at the top of sensor.

[2] Tilt the screwdriver inserted in Step [1] to remove LS-MR1.

To mount the LS-MR1 lens attachment:

[1] The size of upper fixing hook of LS-MR1 is not same as lower fixing hook.

[2] After confirming upper and lower fixing hooks, insert LS-MR1 upper fixing hook into the fixing slot at the top of sensor and then insert LS-MR1 lower fixing hook into the fixing slot at the bottom of sensor.

[3] After mounting, check that LS-MR1 is properly fixed to the sensor.

The cable of the sensor head can be shortened to your desired length. However, it cannot be extended.

Wire connecting procedure:

[1] Process the core length to 7 to 8 mm in accordance with ‘STRIP GAUGE’ indicated on the side of this unit, and twist the core several times. When using shielded wires, twist the wire until obtaining the diameter of φ1.2 mm or less.

Follow these steps to connect the wires:

[1] Use a flathead screwdriver (Blade width: 2 mm or less) to push the operating lever (white) located at the operating area until it is locked.

[2] Insert the wire to the innermost of the wire inlet. Check that the shielded wire is properly inserted into the wire inlet as well as that the core end has passed through the wire connection area.

[3] Place the head of a flathead screw-driver underneath the operating lever (white) through the releasing slot, and lift the screw-driver head. If you hear a snap, the operating lever (white) is returned and the wire is fixed.

[4] Lightly pull the wire to ensure that wire is not loose. When using shielded wires, also check that they do not contact each other.

To release the wire:

Use a flat-head screwdriver (Blade width: 2mm or less) to push the operating lever (white) located at the wire inlet and remove the wire.

The connecting cable pinout is as follows:
