Reflectors

Reflectors are the passive partners to retroreflective photoelectric sensors. The sensor projects a beam at the reflector, which returns it along the same path to the receiver. Anything that breaks the beam triggers detection. Reflectors come in round, square, tape, and prismatic formats sized to match the sensor's beam pattern.

Enicstra stocks reflectors from Banner, SICK, Pepperl+Fuchs, Keyence, Omron, and generic manufacturers — covering current models and obsolete OEM-specific reflectors used in legacy installations. Sizes range from small round reflectors (under 10 mm) for short-range diffuse-mode applications to large heavy-duty reflectors (200+ mm) for long-range outdoor detection. We also stock reflective tape rolls and adhesive-backed reflector strips.

Match the reflector to the sensor manufacturer when possible — the reflector's prism design affects the maximum sensing distance. If you need an OEM-specific reflector not shown, send the original part number. Most quote inquiries reply within 1–2 business days.

Choosing Reflectors components

Reflector selection is mostly about matching the sensor's sensing distance to the reflector's reflectivity and size. A small reflector at the maximum rated range will provide marginal signal — the system works in lab conditions but fails when the reflector accumulates dust or the alignment drifts slightly.

Specifications to confirm before ordering:

Reflector size (diameter for round, dimensions for square)
Sensing distance from sensor to reflector
Sensor manufacturer (reflectors are often optimized for specific sensor families)
Mounting style — bolt-on, adhesive, magnetic, or self-supporting
Environment — indoor, outdoor (UV-resistant), washdown (sealed edges)
Operating temperature range
Resistance to chemicals, vibration, or physical impact

Reflector type guidance:

Standard prismatic reflectors (50–84 mm): the workhorse for general industrial photoelectric sensing
Adhesive tape reflectors: compact, low-cost, suitable for short ranges and confined spaces
Heavy-duty outdoor reflectors: larger, UV-stabilized, often with mounting brackets included
Polarized retroreflective targets: required when the sensor uses polarized retroreflective mode to reject shiny objects
Corner-cube reflectors: very long range, used for outdoor and security applications

Polarized retroreflective sensors require polarization-rotating reflectors — standard prismatic reflectors won't work with them. Check the sensor data sheet before ordering replacement reflectors for a polarized system.

Related categories Frequently asked questions

Do all reflectors work with all photoelectric sensors?

No. Sensor manufacturers often specify reflectors optimized for their products. Generic reflectors usually work but at reduced range. For polarized retroreflective sensors, you must use a polarization-rotating target — standard prismatic reflectors won't work.

Can you supply discontinued OEM reflector part numbers?

Yes — Banner BRT-series, SICK PL-series, Pepperl+Fuchs reflectors, and similar OEM-specific reflectors are commonly available. Even if a generic equivalent works at reduced range, sourcing the OEM part is often preferable for maintenance documentation.

What size reflector should I use?

Match the size to the sensor's specified sensing distance. A small 25 mm reflector might be rated to 1 m; a 50 mm reflector to 2 m; an 84 mm reflector to 7 m or more. Always size up for outdoor or contaminated environments to maintain signal margin as the reflector ages.

Do you carry reflective tape?

Yes — rolls of adhesive-backed prismatic tape are stocked, useful for confined spaces and short-range applications. Tape is more vulnerable to wear than a glass or hard-plastic reflector, so it's not ideal for high-cycle environments.

Are reflectors new or surplus?

Most are new-old-stock or current production. Reflectors don't typically wear out in storage, so even older surplus units perform like new. The product page lists condition where relevant.
