Can detect small objects
Can detect small objects, high detection accuracy, classic square appearance, 25.4mm standard installation hole distance
Stable performance, easy installation.
The detection distance is adjustable and the action state can be switched. The detection distance is adjustable, and the action state (light ON, light blocking ON) can be switched arbitrarily to meet more customer needs. The product has stable performance, strong applicability, and high repetition accuracy. The hysteresis distance is small, the response speed is fast, and it has surge protection circuit, short circuit protection, and polarity reverse connection protection.
Anti-interference
The anti-interference ability of the LS200 model is further enhanced. Equipped with inverter resistance circuit. It can make the peak wavelength optimally offset, so that the product’s resistance to inverter light waves or high-frequency interference of high-voltage variable frequency speed regulation motors is further enhanced.

LS201-RT product for transparent object detection]
Uses a unique optical system and a circuit specifically designed for detecting transparent objects. It can detect all kinds of transparent objects such as transparent films, glass, plastic cups, and other transparent, semi-transparent, and opaque objects.

30m long-distance detection
Can achieve ultra-long-distance detection, suitable for various uses such as automated warehouses or multi-story parking garages.

New economical products are launched
Economical type with a cable length of 0.5m is available, which eliminates the sensitivity adjuster and action switching switch. For applications with clear requirements, the economical type can omit the fine-tuning process on site, achieve quick installation and reduce costs.
Wire outlet method
Two types are available: wire lead-out type (standard) and waterproof plug-in connector type, which helps reduce installation and maintenance hours.
