Product Description

​The Panasonic EX-11EB is an ultra-slim through-beam photoelectric sensor designed for precise object detection in confined spaces. It offers a sensing range of up to 150 mm and features side-sensing capability, making it suitable for applications where space is limited. The sensor operates with a supply voltage between 12 to 24 V DC and consumes minimal current (10 mA or less for both emitter and receiver). It utilizes a red LED light source with a peak emission wavelength of 680 nm and has a rapid response time of 0.5 ms or less. The NPN open-collector output supports a maximum sink current of 50 mA, with residual voltages of 2 V or less at 50 mA and 1 V or less at 16 mA. Housed in a compact enclosure measuring 10 mm (W) × 14.5 mm (H) × 4.5 mm (D), the sensor is rated IP67, ensuring protection against dust and water ingress. It also features short-circuit protection and operates effectively in temperatures ranging from -25°C to +55°C.
