Product Advantages and Features
1.Stable Electrical Performance
Adopting a PNP output design (Gc-PNP), it is suitable for industrial automation control circuits, featuring precise signal transmission and fast response. It can stably adapt to Homag equipment's control systems, reducing misoperations caused by signal interference.
2.Outstanding Durability
As a core component for mechanical limit, it typically offers vibration resistance, dust resistance (suitable for woodworking environments), high temperature resistance, etc. The shell and contact materials are industrial-grade, ensuring a long service life and reducing equipment maintenance frequency.
3.High Positioning Accuracy
Specifically designed for detecting key positions such as feeding and stroke in Homag equipment, it provides high precision in zero-point positioning or limit triggering, directly ensuring the dimensional accuracy and consistency of wood processing (such as edge banding and cutting).
4.Safety Compliance
It meets industrial safety standards and may be equipped with overload protection, short-circuit protection, etc. When the equipment reaches the limit position, it can quickly cut off power or send signals to avoid safety hazards such as mechanical collisions.
These features make it a key component in Homag woodworking machinery for ensuring precision, safety, and efficiency, especially suitable for high-frequency and high-demand industrial production scenarios.

Product Application Scope
The travel switch is widely used in the core woodworking processing equipment of Homag
Ensure stable edge sealing accuracy: In the "zero positioning area" at the feeding end, this limit switch can accurately identify the starting position of the board feeding, ensuring that each board is positioned uniformly, aligning the edge sealing strip with the board edge with an error of ≤ 0.1mm, effectively avoiding edge misalignment caused by feeding deviation, improving the qualification rate of edge sealing products, and reducing waste generation.
Protection of equipment and boards: In the "travel limit zone" of the pressing mechanism, the maximum downward stroke of the pressing wheel can be limited to prevent excessive pressing force from damaging fragile boards such as thin wood veneer and particleboard. At the same time, excessive wear of the mechanical components of the pressing mechanism can be avoided, extending the service life of the core components of the edge banding machine and reducing the frequency and cost of equipment maintenance..
Equipment case: Homag KAL 310, KFL 650 and other fully automatic edge banding machines
