E3Z-D61 Diffuse Photoelectric Sensor | 30cm Range | 12-24VDC NPN/PNP

This diffuse reflection photoelectric sensor finds objects without touching them for your automation projects. It uses an infrared beam to sense things up to 30cm away. It doesn't need a separate reflector. This means the industrial photoelectric sensor is a complete unit that's easy to add to your system. Features and Benefits - Sensing range adjusts from 10-30cm - You can set the detection distance for different targets and machine layouts. - Includes NPN and PNP outputs - You get wiring options to connect with almost any PLC or industrial controller. - Responds in 1ms - It reliably finds fast-moving items on conveyor lines, so you don't miss counts. - Comes with a mounting bracket - You get the hardware you need for a simple installation right away. Applications - Conveyor systems for counting boxes, bottles, or other items for sorting. - Assembly equipment to check if a part is there before the next step starts. - Automated machinery to find where components are for correct alignment. How They Work Photoelectric sensors detect the presence or absence of objects by emitting a beam of light and measuring changes in the reflected light. This E3Z-D61 model uses infrared light. When an object breaks or reflects this light beam, the sensor's output changes, signalling detection. This makes them a reliable choice for automated systems where non-contact detection is crucial. They are often referred to as optical sensors or light sensors due to their reliance on light. 3 Main Types of Photoelectric Sensors There are three primary types of photoelectric sensors. Through-beam sensors have a separate emitter and receiver, detecting an object when the beam between them is broken. Retro-reflective sensors combine the emitter and receiver in one unit, using a reflector to bounce the light back. The E3Z-D61 is a diffuse reflection sensor, meaning it detects objects when its emitted light reflects directly off the object back to the receiver. Common Applications Photoelectric sensors like the E3Z-D61 are widely used in industrial automation and manufacturing. They are ideal for tasks such as counting items on a conveyor belt, detecting the position of components, or verifying product presence. Their 30 cm sensing distance makes them suitable for close-range object detection. This square-shaped sensor, with its NPN and PNP output options, offers versatility in various control circuits. The Core Components Every photoelectric sensor, including this E3Z-D61 model, comprises several key components. It has a light emitter, which in this case uses infrared light. A receiver detects the reflected or interrupted light. There is also an amplifier to boost the signal and an output circuit to communicate the detection status. The robust design, often with mounting brackets, ensures reliable operation in demanding environments. The 3 Main Operating Modes Photoelectric sensors typically operate in three main modes. Light-on mode means the output is active when light is received by the sensor. Dark-on mode means the output is active when no light is received. Some sensors offer both NPN and PNP outputs, like the E3Z-D61, providing flexibility in how they integrate with control systems. This allows tradespeople to configure the sensor to suit specific application requirements.
