What is this product?
The Autonics BEN5M-MDT is a retro-reflective photoelectric sensor that detects objects by sensing the interruption of a light beam bounced back from a dedicated reflector. It's used to detect presence, position, or passage of objects on production lines without needing a separate receiver unit.
Where is it used?
- Conveyor belt systems for object/box detection on packaging lines
- Automated material handling for pallet or bin presence detection
- Elevator door and gate control systems for obstruction detection
- Bottling and filling machines for container presence sensing
- Automated gates and shutters for safety interlocking
Key technical advantages
The BEN5M-MDT stands out for its retro-reflective design, which simplifies installation compared to through-beam sensors since only one side of the line needs wiring — the reflector on the opposite side needs no power or cabling at all, cutting installation time and cost. Its 5-meter sensing range with the supplied reflector gives flexibility for wider conveyor lines or larger gaps than typical diffuse sensors can handle. Autonics builds this sensor with a robust housing rated for industrial dust and moisture exposure, making it reliable in real factory-floor conditions rather than just clean lab environments. The dark-on/light-on selectable output also lets you configure the sensor's logic to match your existing PLC or control panel wiring without needing extra relay logic.

Every order comes with a proper GST invoice, PAN India delivery with fast dispatch from our Delhi (Bhagirath Palace) warehouse, and direct WhatsApp support (+91 98996 68881 / 8800754881) for wiring help, output type open collector simultaneous output, or bulk order pricing.
FAQs
Q: Does the BEN5M-MDT come with the reflector included, or do I need to buy it separately?
A: The BEN5M-MDT is supplied with its matching reflector as part of the package, so you don't need to source it separately — just mount the reflector directly opposite the sensor within the rated 5m sensing distance.
Q: Can the BEN5M-MDT detect transparent or shiny objects like clear bottles or glass?
A: Retro-reflective sensors can struggle with highly transparent or glossy objects since the beam may pass through or reflect unpredictably — for transparent object detection, we'd recommend checking with us about a polarized retro-reflective variant which handles glare and transparency better.
Q: Is the output NPN or PNP on the BEN5M-MDT?
A:open collector simultaneous output
