When you need reliable detection in a limited installation space, a Square Photoelectric Sensor Manufacturer can help you solve both mounting and detection challenges. The LS100 Series from Huayifeng combines a fingertip-sized housing with an 8 mm thickness, allowing you to install the sensor in narrow areas where conventional sensors may not fit. At the same time, its diffuse-reflective and through-beam configurations support different detection requirements, with detection distances of 100 mm and up to 1.5 m. With a response time below 2 ms, NPN output, infrared light, and protection circuits, the LS100 is designed for workpiece positioning, pallet detection, and precision manufacturing applications.
Why Choose a Small Square Photoelectric Sensor?
In automated equipment, sensor dimensions can directly affect machine layout. A bulky sensor may interfere with moving components or leave insufficient space for brackets and wiring.
The LS100 addresses this problem with an ultra-compact square housing measuring only 32.5 × 12 × 8 mm for the relevant configuration. You can place it in narrow installation spaces while maintaining stable object detection.
Key design benefits include:
- 8 mm thickness for compact machine integration
- Diffuse reflection and through-beam models for different detection tasks
- 100 mm diffuse-reflection detection distance
- Up to 1.5 m through-beam detection distance
- 940 nm infrared light source
- Detection of opaque objects 4 mm or larger
- Response time below 2 ms
- One-touch sensitivity adjustment on diffuse-reflective models
- NPN output for industrial control systems
- Surge, short-circuit, and reverse-polarity protection
Square Photoelectric Sensor Manufacturer for Industrial Automation
Huayifeng was established in 2009 and integrates sensor R&D, production, sales, and application support. The company provides standardized and customized sensor products for automation equipment manufacturers and industrial applications.
Its product portfolio covers fiber optic sensors, photoelectric and laser sensors, slot photoelectric sensors, displacement measurement sensors, inductive and capacitive proximity sensors, safety sensors, ultrasonic sensors, pressure sensors, contact sensors, and magnetic sensors.
For the LS100, you can use the sensor in applications such as:
Workpiece Positioning on Processing Lines
On mechanical processing lines, accurate positioning helps equipment confirm whether a workpiece has reached the required position. The LS100 can detect the presence or protrusion of opaque components and provide a fast switching signal to the control system.
Pallet Positioning in Logistics
Long-distance pallet positioning requires sufficient detection range without occupying excessive machine space. The LS101-T1.5MNOD/NCD through-beam configuration provides a detection distance of up to 1.5 m, making it suitable for selected conveyor and logistics positioning tasks.
Precision Manufacturing
When you need to identify small objects or confirm component presence, detection accuracy becomes important. The LS100 supports detection of opaque objects from 4 mm, while its sub-2 ms response time helps you capture fast-moving events.

How to Select the Right LS100 Configuration
Before integrating a small photoelectric sensor into your equipment, follow these steps:
- Define the detection target: Confirm the size, shape, and material of the object you need to detect.
- Measure the installation space: Check whether the 8 mm-thick LS100 housing fits between mechanical components.
- Select the optical principle: Choose diffuse reflection for direct object detection or through-beam for longer-range applications.
- Confirm the detection distance: Use the 100 mm diffuse-reflection model or the 1.5 m through-beam model according to your layout.
- Check the control interface: Confirm that the NPN output and 12–24 V DC supply match your control system.
- Fine-tune sensitivity: For diffuse-reflective models, use the built-in sensitivity adjustment to optimize detection performance.
