Product Description

​The Omron E3Z-LT61 is a compact laser photoelectric sensor with a built-in amplifier, designed for precise and reliable detection over long distances. Utilizing a through-beam sensing method, it offers a sensing distance of up to 60 meters, making it suitable for applications requiring extended reach. The sensor emits a red laser light at 655 nm wavelength and features a response time of 1 millisecond, ensuring quick detection and minimal delay. It operates on a 12 to 24 VDC power supply and has a current consumption of 35 mA (15 mA for the emitter and 20 mA for the receiver). The NPN open collector output can handle up to 100 mA with a residual voltage of 1 V max. when the load current is less than 10 mA. The device is housed in a durable IP67-rated enclosure, providing protection against dust and water ingress, making it suitable for demanding industrial environments.
