Best Kemo products in the Development board accessories category
On this page you'll find a ranking of the best Kemo products in this category. To give you a quick overview, we've already ranked the most important information about the products for you.
1. Kemo Light barrier IR Light barrier
The invisible infrared light beam makes the light barrier ideal for alarm and surveillance systems. When the light beam is interrupted, the relay activates for the duration of the interruption.

2. Kemo Mono amplifier sal 12 W Plug & Play
The amplifier module is equipped with a cinch socket for signal input, a socket for power supply, built-in volume control, and a cable for speaker connection.

3. Kemo Timer (short) approx. 2 sec. - 5 min.
The Kemo B042 timer switch is a versatile kit designed for applications where a time-controlled circuit is required. With an operating voltage of 12 V/DC, this timer switch allows for precise control of electrical devices over an adjustable period ranging from 2 seconds to 5 minutes. The switching process is activated by a button press, which turns the integrated relay on for the selected duration and then turns it off again. This product is ideal for various electronics projects and provides an easy way to integrate time controls into circuits. The kit is compact and can be easily integrated into existing systems, making it a practical choice for developers and hobbyists.
- Adjustable switching times from 2 seconds to 5 minutes
- Operating voltage of 12 V/DC
- Current consumption of approximately 40 mA
- Compatible with the matching housing G024N.

4. Kemo Rain sensor capacitive
If the fully insulated sensor plate gets wet (e.g. raindrops), then a relay switches on. Unlike rain detectors with a metal sensor, this sensor works capacitively. This means that it also switches when it comes into contact with distilled water (when the rain is completely clean). This means that skylights can be
closed, awnings retracted or only rain can be reported. 2 built-in LEDs indicate the function. The sensitivity is adjustable.

5. Kemo light gate
Switches a relay in light or darkness (shadow). When the light beam from a lamp is interrupted by a person at doors, windows, etc., the device triggers an alarm. It can also be used as a dusk switch.

6. Kemo Timer
Switches other devices on with the built-in relay contact after a button press and automatically turns them off again after the set time. The timer can be stopped at any time by pressing the second button. Two push buttons are also required for operation.

7. Kemo Ultrasonic distance warning
This device operates based on the ultrasonic echo principle. When an object comes within 10 to 80 cm of the ultrasonic sensor, an LED lights up. Applications include: parking assistance in garages, alarm system for people or animals, object detection on conveyor belts, theft monitoring of larger items, and more.

8. Kemo Amplifier module
Robust amplifier module for universal use as a loudspeaker power amplifier. The module is encapsulated to be moisture and vibration resistant. The potting compound and the module housing are made of a special, highly heat-conductive plastic. No additional heat sink is required. The module is electronically protected against overheating and overloading.

9. Kemo Slave Switch /Slave
Automatically switches on another load when a machine, lamp, etc. is turned on. It can monitor single-phase or three-phase (three-phase) machines (with one phase being sampled). On the output side, single-phase devices (e.g., vacuum cleaners) can be automatically switched on (or three-phase consumers via an auxiliary relay, not included). Max. 15 A each, max. total power: 3600 W.

10. Kemo Mono amplifier module
The module is encapsulated to be moisture and vibration resistant. The encapsulation material and the module housing are made from a special, highly thermally conductive plastic. The module is electronically protected against overheating and overload.
