The Photoelectric Switch-E3F-DS30B2 is an industrial sensor that detects objects by emitting an infrared light beam and sensing the reflection from the object. This model operates on DC power and provides an NPN Normally Closed (NC) output, meaning its circuit is conducting current until an object is detected, upon which it opens (stops current flow). It's commonly used in automation for reliable, non-contact object presence detection over an adjustable range.
Features of the Photoelectric Switch-E3F-DS30B2:
- Diffuse Reflection Sensing: Emits infrared light and detects objects by sensing reflected light from the object itself.
- DC Power (NPN NC Output): Operates on DC voltage (6-36V) and provides an NPN Normally Closed output, meaning the circuit is usually closed and opens upon detection.
- Non-Contact Detection: Senses objects without physical touch, reducing wear on both the sensor and the detected items.
- Cylindrical M18 Design: Features a standard M18 cylindrical housing for straightforward industrial mounting.
- Adjustable Sensing Range: Includes a sensitivity adjuster to fine-tune its 7-30cm detection range for various applications.
- Built-in Protection: Incorporates reverse connection protection, surge absorption, and load short-circuit protection for enhanced durability.
- Status Indicator: Equipped with a red LED that provides visual feedback on the sensor's operating status and detection events.
- Robust Construction: Designed with IP65/IP67 protection against dust and water, suitable for harsh environments.
