Description

The M4 FTD-04NO photoelectric switch operates on the diffuse reflection principle, where its integrated laser emitter and receiver detect objects within a 50mm range by sensing the reflected light. This self-contained sensing method eliminates the need for a separate reflector, simplifying installation in confined spaces.

Built with a stainless steel M4 threaded body, the sensor is designed for durability in industrial environments. Its internal circuitry features synchronous loop gating for enhanced noise immunity and stable operation across a 0°C to 50°C temperature range, ensuring reliable performance in factory automation and packaging machinery.

Key Features

  • Diffuse-reflective optical design for straightforward single-unit installation.
  • Stainless steel M4 threaded housing provides corrosion resistance and mechanical strength.
  • Integrated synchronization circuit offers strong anti-interference capability against ambient light.
  • Low 9mA no-load current contributes to energy-efficient system design.
  • Wide operating temperature range (0°C to 50°C) supports use in varied industrial settings.
  • High 120Hz response frequency enables detection in fast-moving production lines.

Applications

  • Object presence verification and counting on conveyor belts and assembly lines.
  • Small-part detection and positioning in compact robotic grippers and feeders.
  • Jam detection and end-of-travel sensing in automated packaging machinery.
  • Level detection for small containers or vials in pharmaceutical and lab automation.

Frequently Asked Questions

What is the wiring diagram for the M4 FTD-04NO photoelectric switch?

The sensor uses a standard 3-wire configuration: connect the brown wire to the positive DC supply (10-30V), the blue wire to the negative/common ground, and the black wire as the NPN open-collector output. The output switches to ground (sinks current) when an object is detected within the 50mm range.

Can this sensor detect transparent or shiny objects?

Detection of transparent or highly reflective objects can be unreliable with diffuse reflective sensors, as they depend on sufficient light being scattered back to the receiver. For such materials, a through-beam or retro-reflective sensing mode is generally recommended for consistent operation.

What is the meaning of the '04NO' in the model number?

The '04' typically denotes the M4 threaded housing size. 'NO' stands for Normally Open, indicating the output transistor is off (open circuit) when no object is present and switches on (closes to ground) when a target is detected within the sensing range.

Is this sensor suitable for outdoor use or wet environments?

No. The M4 FTD-04NO has no specified IP rating for dust or water ingress protection. It is designed for indoor, relatively clean industrial environments. Its operating temperature is limited to 0°C to 50°C, and it should not be exposed to rain, condensation, or direct washdown.
