Omron E3Z-G81 Photoelectric Switch
The Omron E3Z-G81 Photoelectric Switch is a grooved type photo microsensor. It has a sensing distance of 25 mm, allowing for accurate detection of opaque objects. The sensor can detect objects with a minimum diameter of 1.5 mm. It utilizes an infrared LED light source with a wavelength of 940 nm. The sensor operates with a power supply voltage ranging from 12 to 24 VDC. It consumes a maximum current of 25 mA during operation. The sensor offers Light-ON/Dark-ON selectable operation modes to suit different detection requirements. Additionally, it is equipped with protective circuits for output short-circuit and power supply reverse polarity protection.
The E3Z-G81 operates within an ambient temperature range of -25 to 55 ℃ during operation. During storage, it can withstand temperatures from -40 to 70 ℃. Humidity levels during operation range from 35 to 85%. During storage, humidity levels can vary from 35 to 95%.It boasts vibration resistance up to 55 Hz and shock resistance up to 500 m/s2, ensuring durability in industrial environments. Additionally, it has an IP64 degree of protection according to IEC standards, making it resistant to dust and water ingress.
The Omron E3Z-G81 Photoelectric Switch comes with pre-wired models featuring a cable length of 2 m for easy installation and weighs approximately 65 g, constructed with a case made of ABS material. Originating from China, the Omron E3Z-G81 is a reliable solution for various object detection applications in industrial settings.
