Overview of SICK OLM100 Linear Measurement Sensor
The OLM100 is a linear positioning sensor from SICK that uses barcode camera technology, belonging to the Linear Measurement Sensors product family. The device reads a special barcode tape to determine the absolute position of moving equipment on rails or conveyors.
Unlike conventional encoders (rotary encoders), the OLM100 requires no mechanical contact parts, resulting in significantly longer service life and lower maintenance costs.
This sensor is ideal for applications requiring high-accuracy positioning at high speeds in harsh industrial environments, with an operating temperature range from -30°C to +60°C.
Key Features:
- Absolute positioning with a measuring range of up to 10,000 meters
- Maximum travel speed of 4 m/s (standard version)
- Repeatability of 1 mm (standard version)
- Adjustable resolution of 0.1 mm or 1 mm
- Non-contact, wear-free operation thanks to barcode camera technology
- Compact and extremely robust magnesium die-cast housing with excellent vibration resistance
- Versatile interfaces: SSI, RS-422, RS-485, CANopen
- Wide operating temperature range: –30°C to +60°C, protection rating IP65

Industrial Applications of SICK OLM100 Linear Measurement Sensor
With its extremely long measuring range and high accuracy, the SICK OLM100 is suitable for many linear positioning applications in Vietnamese factories:
Electric Overhead Conveyor (EHB / EMS):
The OLM100 is mounted on the moving trolley to read the barcode tape along the rail, providing precise positioning for each carrier. With speeds up to 4 m/s and resolution of 0.1 mm, it enables efficient coordination of multiple vehicles without requiring mechanical encoders. Ideal for automotive, electronics, and textile manufacturing plants.
Automated Storage and Retrieval Systems (AS/RS – Stacker Crane):
Precise positioning of the horizontal and vertical travel of pallet handling machines in high-bay warehouses. The 10,000 m measuring range covers the entire warehouse length, while the SSI interface delivers position data directly to servo drives without additional signal converters.
Overhead Cranes and Industrial Cranes:
Provides absolute position feedback for bridge cranes moving across the factory, supporting anti-collision functions between multiple cranes on the same rail. The robust magnesium housing and wide temperature range make it suitable for mechanical workshops and metallurgical environments.
Turntables and Transport Skids:
Integration into assembly lines with circulating skids. Since the OLM100 is non-contact, it eliminates mechanical wear and reduces periodic maintenance costs.
