Waterproof IP67
Featuring waterproof IP67 to allow use in the presence of large amounts of water or dust.
Simple positioning
Check the optimal receiving location at a glance while watching the red spot on the beam axis adjustment screen.
1 m 3.281 ft sensing range(In STD amplifier response time mode)
The LS-H102 delivers sufficient sensing range for use with 450 mm 17.717 in wafers.
Two-point installation
The thru-beam type LS-H102 features the same form as the EX-L200 amplifier built-in ultra-compact laser sensor. And it can be used as an EX-L200 with a digital indicator.
Industry’s smallest* + Thinnest profile
*Amplifier-separated type laser sensor head as of September 2014, in-company survey
Featuring a 60% smaller design (by volume) than previous coaxial reflective models
Our smallest unit is smaller in every dimension at just W8 × H23 × D18 mm W0.315 × H0.906 × D0.709 in (excluding indicators).
Coaxial design
By using a laser with high linearity in a coaxial design, the LS-H201 is able to deliver stable sensing in confined spaces as well as simple installation.
Small, long-range spot
The LS-H201 produces a spot with a diameter of 2 mm 0.079 in at a sensing range of up to 300 mm 11.811 in (in STD amplifier response time mode).
Easy-to-see operation indicator
The LS-H201’s operation indicator is visible from all directions.
Industry’s smallest* + Horizontal symmetry
* Amplifier-separated type laser sensor head as of September 2014, in-company survey
Horizontal symmetry
Featuring a simple system design process thanks to a light source that is placed in the center of the sensor head and a coaxial design.
Industry’s smallest* and thinnest design
The LS-H901 is even thinner than previous models, measuring just W8 × H23 (excluding indicators) × D18 mm W0.315 × H0.906 × D0.709 in.

Maximum compatibility with fiber sensors
The LS-500 series features the same operation, menu displays, and form factor as the FX-500 series for increased compatibility with fiber sensors.
Detection of beam axis misalignment
Dual outputs (self-diagnosis output)
The LS-500 series can detect any reduction in incident light intensity, for example due to the accumulation of dirt such as dust, and issue an alarm. Sensing output 2 can be set as self-diagnosis output. When you teach the threshold for sensing output 1, sensing output 2 is set accordingly, allowing you to shift the threshold by a previously set margin.
Stable sensing over the long term
The LS-500’s threshold-tracking function helps maintain stable sensing over the long term and reduce maintenance man-hours. The incident light intensity can be checked and the threshold automatically reset at a user-selected interval to track changes in light intensity due to environmental changes (such as dust, etc.) over extended periods of time.
Logic operations
The LS-500’s ability to perform three logic operations (AND, OR, and XOR) on a standalone basis eliminates the need for a dedicated controller, cuts down on wiring, and lowers costs. This functionality can also be combined with the FX-500 series.
Data bank
Eight sets of amplifier settings can be stored in the unit’s built-in memory. The ability to save and load settings reduces workload when changing the setup in a multimodel production environment.
Network communication possible
Can connect to Open Network CC-Link IE Field / CC-Link / DeviceNet / EtherCAT via Communication Unit for Open Network SC-GU3 series. Monitoring and various settings can be done from PLC, PC, etc.
