The probe of the -H211 infrared sensor switch is made of environmentally friendly aluminum alloy, which is beautiful and . The probe has high resistance after oxidation treatment. It is suitable for use in humid environments. The sensor window uses a special filter. The high-speed signal processing chip is used on the board, which is not afraid of the interference of lights and sunlight, and can be used normally in a strong light environment, and the sensing distance is unchanged; the sensing is sensitive, and the detection program has been used for a long time, and the detection error is zero; Small size, light weight, easy to install and fix, high load power, low heat when working at full load. Voltage: AC85-250V Working temperature: -20~55 Celsius Size: 100x43x21mm Current: Max.2A Instructions for use 1. Punch holes of the corresponding size for the panel to be installed, then put the sensor probe into the hole, tighten the nut, and place the fixing glue on the nut to avoid vibration and loosening after long-distance transportation after installation. 2. After connecting the sensor probe, connect the output terminal of the controller (note the polarity of L and N), and then connect the input terminal of the controller (note the polarity of L and N), and check the wiring. After the error is correct, it can be powered on. Colour: white Material: plastic Package Contents: 1 * -211 open close Switch Only the above package content, other products are not included.
