PANASONIC LS-H92 (01) PDF Document

No, never use the PANASONIC LS-H92 as a sensing device for personnel protection. In case of using sensing devices for personnel protection, use products which meet standards for personnel protection applicable in each region or country.

The PANASONIC LS-H92 is a laser product. Do not view the direct beam with the unprotected eye or with an optical instrument, as lasers are potentially hazardous. Use of control or adjustment or performance of procedures other than those specified in the manual may result in hazardous radiation exposure.

The PANASONIC LS-H92 is classified as a Class 2 laser product according to IEC 60825-1-2014 and JIS C 6802-2014 standards.

A Class 2 laser product emits a visible beam at low power, where the blink response of the eye affords protection.

While the laser is being emitted, the green laser emission indicator on the PANASONIC LS-H92 sensor head lights up. This indicator remains visible even when wearing laser protective glasses.

The operating ambient temperature for the PANASONIC LS-H92 is -10 to +55 degrees Celsius with no dew condensation or icing allowed. The storage temperature range is -20 to +70 degrees Celsius. The ambient humidity for both operating and storage is 35 to 85 percent RH.

The sensing range for the PANASONIC LS-H92 depends on the mode of the applicable amplifier:

H-SP mode: 0.2 to 10m

FAST mode: 0.2 to 10m

STD mode: 0.2 to 20m

U-LG mode: 0.2 to 30m

No, you should always use the PANASONIC LS-H92 along with the optional exclusive amplifier. Using a different amplifier may cause the product to not meet its specifications, or it may lead to malfunction or breakdown.

If noise-generating equipment such as a switching regulator or inverter motor is used in the vicinity of the PANASONIC LS-H92, connect the frame ground (F.G.) terminal of that equipment to an actual ground.

No, do not use the PANASONIC LS-H92 during the initial transient time of 0.5 seconds immediately after the power supply is switched on.

Do not run the wires of the PANASONIC LS-H92 together with high-voltage lines or power lines, and do not put them in the same raceway. Doing so can cause malfunction due to induction.

The sensor head cable of the PANASONIC LS-H92 cannot be extended. Also, ensure that no stress is applied to the sensor head cable joint.

Do not allow water, oil, fingerprints, dust, or dirt to stick to the emitting/receiving surfaces of the PANASONIC LS-H92, as these may refract or block light. If they are present, wipe them off using a clean, soft cloth or lens paper. Ensure the power is off while cleaning these windows.

In principle, the coaxial retroreflective type PANASONIC LS-H92 may be unable to detect a mirror object or an object that easily diffuses the receiving light at a short sensing distance because the polarized light becomes unstable. If this occurs, you can lower the receiving light sensitivity with the M.G.S. function of the amplifier, change the response time, or increase the distance between the sensor head and the sensing object.

The sensing distance for the PANASONIC LS-H92 depends on the receiving light sensitivity set via the M.G.S. function, using the RF-230 reflector as a reference:

For H-SP and FAST response time modes: Level 3 is 10m, Level 2 is 4m, Level 1 is 3m.

For STD response time mode: Level 3 is 20m, Level 2 is 8m, Level 1 is 5m.

For U-LG response time mode: Level 4 is 30m, Level 3 is 20m, Level 2 is 10m, Level 1 is 7m.

The tightening torque for mounting the PANASONIC LS-H92 should be 0.5N meter or less. When placing the sensor horizontally or vertically, the reflector must also be positioned horizontally or vertically. If the reflector is tilted, the reflection amount will decrease, which may cause unstable detection.

Follow these steps to connect the wire:

1. Process the core length to 7 to 8 mm according to the STRIP GAUGE on the unit, and twist the core several times. For shielded wires, twist the wire until the diameter is 1.2 mm or less.

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

3. Insert the wire to the innermost of the wire inlet, checking that the shielded wire is inserted and the core end has passed through the wire connection area.

4. Place the head of a flathead screwdriver underneath the operating lever through the releasing slot, and lift the screwdriver head. A snap sound indicates the lever has returned and the wire is fixed.

5. Lightly pull the wire to ensure it is not loose, and check that shielded wires do not contact each other.

The terminal assignments for the PANASONIC LS-H92 are as follows:

Terminal 1: Conductive core (Brown)

Terminal 2: Shielded wire (Gray)

Terminal 3: Conductive core (Yellow)

Terminal 4: Shielded wire (Black)

To release a wire from the PANASONIC LS-H92 connector, use a flathead screwdriver with a blade width of 2mm or less to push the operating lever (white) located at the wire inlet, then remove the wire.
