Think about all the surfaces you touch in a single day. Door handles, elevator buttons, light switches, water dispensers. Each touch is a potential transfer point for germs. Now imagine a switch that requires no physical contact at all. The ABILKEEN 19mm and 22mm IP68 waterproof metal infrared sensor switches bring this contactless future to access control, sanitary facilities, industrial equipment, and smart home automation. By simply passing a hand within the detection field, the switch activates—no pressure, no contact, no cross-contamination. ABILKEEN has engineered a switch that responds to presence, not pressure.

Let us talk about how the technology works. The switches utilize infrared proximity sensing that triggers when an object—such as a hand—passes within the detection field. The sensor emits an infrared beam and detects its reflection off nearby objects. When the beam is interrupted by something entering the detection zone, the switch activates. This contactless operation reduces cross-contamination risks in sanitary environments and provides convenient activation when hands are full, gloved, or soiled. The sensing distance is adjustable from 2cm to 10cm, allowing installers to fine-tune sensitivity for specific application requirements. Whether you need a short-range sensor for a water dispenser or a longer-range sensor for a door entry system, ABILKEEN gives you the flexibility to set it right.

The IP68 waterproof construction is another cornerstone of this series. Each switch features a stainless steel housing with full IP68 ingress protection, ensuring reliable operation in environments exposed to moisture, dust, and even prolonged submersion. This is not a splash-proof rating; it is full immersion protection. We have tested these switches submerged in water for extended periods, and they continue to function flawlessly. The metal construction delivers excellent corrosion resistance and mechanical durability, making these switches suitable for outdoor installations, marine applications, food processing facilities, and other harsh-condition settings. ABILKEEN builds switches that survive where ordinary sensors fail.

Integrated LED illumination provides clear visual confirmation of switch status. The bi-color LED transitions from one color to another—red to green or green to red—to indicate whether the sensor has been activated. This visual feedback helps operators quickly verify that the switch has registered their input. For example, green could indicate "ready" and red could indicate "activated." Color options include red, green, blue, white, and yellow, with single or bi-color configurations available. The LED is bright enough to be seen in daylight yet subtle enough to avoid distraction in low-light environments. ABILKEEN has designed the visual feedback to be intuitive at a glance.

The series offers extensive customization to match diverse application needs. Mounting diameters are available in 19mm and 22mm panel cutouts, the two most common sizes for industrial and commercial control panels. The rated voltage is 12-24V DC, compatible with most control systems and power supplies. The rated current of 1000mA handles a wide range of loads directly. The action pattern is momentary reset operation—the switch activates while the object is detected and deactivates when the object is removed. The contact form is a contactless electronic switch, meaning there are no mechanical contacts to wear out. The electrical life is rated at 1 million cycles, ensuring long-term reliability. The operating temperature spans -25°C to +55°C, covering most indoor and outdoor environments. Termination is via pre-wired cable assembly, simplifying installation.

The flexibility of these IR proximity sensors makes them suitable for a wide range of use cases. They can be programmed to unlock electronic door locks when an object passes in front of the sensor—ideal for hands-free entry systems in offices, hospitals, and clean rooms. Alternatively, they can trigger alarms when an object is removed from the sensing area, making them equally effective for anti-theft applications in display cases and exhibitions. Common installations include water dispensers, hands-free entry systems, sanitary facilities, industrial equipment, and smart home automation. The ability to switch between these functions with simple configuration changes makes the ABILKEEN IR sensor a versatile tool for system integrators.

Certain variants of the series incorporate stepless dimming functionality, adding another layer of capability for lighting applications. With this feature, the initial brightness is 100% at power-on. A short click (under 550ms) toggles the light on and off—simple on/off control. Touching and holding for over 550ms initiates smooth brightness adjustment. Brightness increases during sustained contact and holds at the level when contact is released. Holding beyond three seconds drives brightness to maximum; repeating the action decreases brightness to minimum. This intuitive dimming logic works seamlessly with the contactless sensor, allowing users to adjust lighting without ever touching a physical control. ABILKEEN has combined two powerful technologies into a single, elegant solution.
