Product Description
Product Introduction
The Ultra-Small 95 Series Slot Sensor is a high-performance photoelectric sensor designed for space-constrained applications. With its ultimate compact size (only 25mm series specifications) and excellent detection performance, this series of products has shown unique advantages in the fields of micro automation equipment, precision electronic assembly, medical equipment, etc. This product adopts innovative optical design and high-precision manufacturing processes to achieve detection performance comparable to traditional large sensors in a tiny package.
Equipped with two independent outputs
All models are equipped with two independent outputs - ON when light enters and ON when blocked, which can meet different output requirements according to different places of use.
Note: Only the used cables need to be connected (ON when light comes in or ON when blocked). For unused output lines, be sure to insulate them.

Easy connection
The simple connection type eliminates all the troubles such as soldering and insulation that were required in the past to achieve quick connection, which is very simple.

Wire lead out
Standard 2M flexible wire, the wire length can be customized.
Optional bending resistant drag chain line-GR.
Optional white normally open and black normally closed-SX.
Wide voltage range
The power supply voltage range is 5~24VDC.
High speed response
The response frequency is 3KHZ high-speed response.
