・	This website is a guide to select a suitable product. Be sure to read the instruction manual attached to the product prior to its use.

Never use this product as a sensing device for personnel protection.
In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.

Cautions for laser beams

This product is classified as a “Class 1 laser product” by IEC, EN, JIS, GB, KS standards and FDA regulations^*.
Avoid observing beams in a dark surrounding environment.
Do not stare into laser beam with an optical device such as telephoto optics.
Never disassemble, repair or modify the product.
The following label is attached to the cable. Handle the product according to the instruction given on the warning label.

^*	This product complies with 21 CFR 1040.10 and 1040.11 Laser Notice No. 56, dated May 8, 2019, issued by CDRH (Center for Devices and Radiological Health) under the FDA (Food and Drug Administration).

Safety standards for laser beam products

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 and FDA Regulations.

	IEC	: IEC 60825-1:2014
	EN	: EN 60825-1:2014/A11:2021
	JIS	: JIS C 6802:2014
	GB	: GB 7247.1-2012
	KS	: KS C IEC 60825-1:2014
	FDA	: PART 1040.10, 1040.11(Laser Notice No.56 applied)

These standards classifies laser products according to the level of hazard and provide the safety measures for respective classes. Based on the above standards, EX-L200 series is classified as a Class 1 laser product.

Classification	Description
Class 1	Lasers that are safe under reasonably foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing.

Note: When an unexpected failure occurs, dangerous radiation may be generated. Therefore, pay special attention to safety.

Safe use of laser products

For the purpose of preventing users from suffering injuries by laser products, each standard stipulates (Safety of laser products).Kindly check the standards before use.

Mounting

When mounting this sensor, use a mounting plate (MS-EXL2-2, MS-EXL2-3). Without using the mounting plate, beam misalignment may occur. Also, install the mounting plate in between the sensor and the mounting surface.
The tightening torque should be 0.5 N·m or less.

Note:	The mounting direction of the mounting plate is fixed. Install in a way so that the bending shape is facing the sensor side.

Automatic interference prevention function

Spot reflective type sensor incorporate this function.
Up to two sets of sensor can be mounted closely.
(Thru-beam type sensor does not have this function.)

2 sensor heads can be mounted adjacently.

Note:	If two spot reflective type sensor are mounted facing each other, they should be angled so as not to receive the beam from the opposing sensor or to detect its front face.

Automatic interference prevention function Incorrect Correct

Others

Do not use during the initial transient time (approx. 50ms) after the power supply is switched ON.
In case the load and this sensor are connected to different power supplies, be sure to turn ON the power from the sensor.
The cable may break by applying excess stress in low temperature.
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 this sensor in places having excessive vapor, dust, etc., or where it may come in contact with corrosive gas.
Take care that the sensor does not come in direct contact with oil, grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.
Make sure that the power is OFF while cleaning the emitting / receiving windows of the sensor head.
This device is using a laser which has high directional quality. Therefore the beam possibly be out of alignment by the mounting condition of this device or distortion of housing etc. Make sure to adjust the beam axe alignment before use.
