Optical slot motor speed sensor

The Optical Slot Motor Speed Sensor is a non-contact sensor designed to measure the rotational speed of motors and other rotating components. This sensor uses an optical slot (also known as a slotted optical switch) to detect interruptions in the light beam, which are caused by the movement of a slotted disk attached to the rotating shaft. This allows for accurate measurement of speed, position, and direction of rotation in various applications, including industrial automation, robotics, and motor control systems.

Key Features:

• Non-Contact Measurement: Utilizes an optical slot for contactless speed detection
• High Accuracy: Provides precise measurements of rotational speed
• Wide Speed Range: Suitable for measuring a broad range of rotational speeds
• Easy Integration: Compatible with microcontrollers and other electronic systems
• Durable Design: Robust construction for reliable performance in various environments
• Compact Size: Small form factor for easy integration into tight spaces

Technical Specifications:

• Sensing Method: Optical slot (slotted optical switch)
• Supply Voltage: 5V DC (typical, may vary by model)
• Output Type: Digital (pulse signal)
• Output Format: Typically open-collector output
• Sensing Distance: Typically up to 5mm (depends on slot width and disk design)
• Slot Width: Varies by model, typically around 3mm to 5mm
• Response Time: Fast response suitable for high-speed applications
• Operating Temperature Range: -25°C to +85°C
• Dimensions: Varies by model, typically compact

Applications:

• Motor speed measurement and control
• Position and direction sensing
• Industrial automation systems
• Robotics and motion control
• Tachometers and RPM meters
• Conveyor belt systems

Usage:

1. Attach the slotted disk to the rotating shaft of the motor or component you wish to measure.
2. Position the optical slot sensor such that the slotted disk passes through the sensor’s slot, interrupting the light beam.
3. Connect the sensor to a microcontroller or data acquisition system using the digital output.
4. Power the sensor with the appropriate supply voltage (typically 5V DC).
5. Read the output pulses to measure the speed and position of the rotating component.

Caution:

• Ensure proper alignment of the slotted disk and sensor for accurate measurements.
• Verify the supply voltage to prevent damage to the sensor.
• Handle with care to avoid damage from physical impact or electrostatic discharge (ESD).
