Fiber Optic Through-beam Sensor Bracket

A fiber optic through-beam sensor mounting bracket securely holds the sensor and its fiber optic heads in precise alignment for reliable detection in industrial applications.

Purpose and Function

Fiber optic through-beam sensors detect objects by transmitting light from a transmitter fiber to a receiver fiber across a target area. A mounting bracket ensures that both the transmitter and receiver heads are accurately aligned, stable, and protected from vibrations or misplacement, which is critical for consistent sensor performance . These brackets are particularly important in harsh environments or tight spaces where fiber optic sensors are preferred due to their small sensing heads and lack of electronics in the detection area .

Types and Features

• Material and Construction: Brackets are typically made from durable materials such as aluminum or high-strength plastics to withstand industrial conditions . Some are flexible resin or PA (66N) black material for resilience and vibration mitigation .
• Design Variations: Options include single-plate brackets, flexible square shaft brackets, and post stand sets. These designs allow mounting on flat surfaces, plates, or posts, and can accommodate both round and square shafts .
• Compatibility: Brackets are often designed to fit specific sensor models or series, such as IFM's E20827 fiber optic through-beam sensor, and may include sets for light curtains or multiple sensor heads . Some brackets are supplied as sets of two pieces for paired transmitter and receiver installation .
• Ease of Installation: Many brackets allow quick installation with pre-included stands or pipe shafts, reducing setup time and enabling easy adjustments for alignment . CAD drawings and mounting instructions are often provided by manufacturers for precise installation .

Sourcing and Accessories

• Manufacturers: Companies like IFM, KEYENCE, MISUMI, and Proxitron offer mounting brackets and accessories for fiber optic sensors .
• Additional Accessories: Some brackets can be paired with oven windows for high-temperature applications, fiber adapters, or attenuators depending on the sensor setup .
• Customization: Many suppliers provide custom lengths, materials, or configurations on request to suit specific industrial requirements .

Installation Tips

1. Ensure the bracket is mounted on a stable surface to prevent misalignment.
2. Align the transmitter and receiver fibers carefully to maximize signal detection.
3. Use vibration-resistant materials or flexible mounts if the environment is prone to mechanical disturbances.
4. Refer to manufacturer CAD drawings and instructions for precise positioning and spacing .

Using the correct mounting bracket ensures reliable detection, long-term stability, and optimal performance of fiber optic through-beam sensors in industrial automation and harsh environments.
