SICK BEF-1SHABPKU4 FlexFix Bracket

BEF-1SHABPKU4 is a SICK FlexFix bracket (part no. 2066614) for two devices, for example a sender and a receiver of a through-beam pair. It is made of plastic, can be aligned by +/- 15 degrees and includes an M5 screw. The packing unit is 4 pieces.

FlexFix alignment for two devices on one bracket

The FlexFix idea is a bracket with a pivot, so the beam of a through-beam or retro-reflective pair can be aligned without bending a bracket. Each bracket takes two devices, which helps when sender and receiver are fixed side by side or on a common support, and it saves fitting separate adjustment hardware.

The data sheet gives the description: flexFix bracket for 2 devices (e.g. sender and receiver), can be aligned ± 15°, including M5 screw Mounting kit 2, mounting bracket, pivots. The material is plastic and the product is sold in packs of 4 pieces, so one order covers several brackets; check how many devices you need to mount and whether the pack size suits you.

Technical specifications

Type code BEF-1SHABPKU4 and part number 2066614

SICK groups brackets under the BEF prefix; the letters and digits after it name the device family or the bracket concept. The part number 2066614 is the safe way to identify this bracket, and it is listed under Mounting systems / Brackets in the SICK catalogue. A similar looking bracket with a different number will have a different hole pattern.

Selection and fitting notes

Check the dimensional drawing in the data sheet for hole spacing and clearance before you drill. Use fasteners of a material compatible with the bracket, observe the maximum tightening torque of the sensor you mount, and re-check alignment after tightening. Brackets are accessories, so no electrical data apply. Quantity matters with this item: the packing unit is 4 pieces and one FlexFix bracket carries two devices, so a through-beam pair needs one bracket and a pack covers four pairs. Tell us the number of devices you are mounting so we can confirm the quantity. To align, loosen the pivot, point the pair at each other while watching the received-light indication of the receiver, then tighten the M5 screw. A plastic bracket is not meant for heavy loads or hot machinery, so check the ambient conditions at the mounting point.

Planning the mounting position

Before ordering, walk the machine or conveyor and mark where each sensor pair will sit. Look at what surrounds the bracket: moving parts, product that could knock against the sensors, cleaning access and the route the sensor cables will take. A FlexFix bracket gives a limited alignment range of ± 15°, so the support it is fixed to should already face roughly in the right direction; the pivot is intended for fine adjustment, not for correcting a badly placed support. Confirm that the sensors you plan to fit match the hole pattern on the SICK dimensional drawing, since compatibility is decided by the drawing and not by appearance.

Where several pairs are mounted close together, consider how the beams of neighbouring pairs might interfere, and leave enough space around each bracket for a hand and a tool to reach the M5 screw later.

Installation and alignment routine

Fix the bracket to a rigid, flat surface so that vibration from the machine frame does not shift the beam over time. Mount the sensors loosely first, route and secure the cables with some slack so they do not pull on the sensor, then carry out the alignment. Make small movements on the pivot, check the sensor indication after each step, and aim for the middle of the range in which the beam is detected rather than the very edge. Once the M5 screw is tight, test the function with a real object passing through the beam, at the speed the line will actually run.

Maintenance checks in service

Plastic brackets need little attention, but a short check during planned stops is worthwhile. Confirm that the screw is still tight, that the bracket shows no cracks or deformation, and that the sensors have not been knocked out of line by cleaning, product jams or maintenance work nearby. If a sensor pair starts to give intermittent signals, re-check alignment before replacing electronics, because a shifted bracket is a common and simple cause. Record the final alignment position with a mark or photo so it can be restored quickly after a sensor change.

Heat, dust and humidity in Oman and the GCC

Warehouses, packing halls and outdoor conveyors in the region can be hot, dusty and, near the coast, humid. Since the bracket is plastic, avoid placing it against hot surfaces, in direct strong sunlight or close to heat sources, and check the ambient conditions at the mounting point against the SICK documentation. Dust settling on sensor optics affects detection more than the bracket itself, so include lens cleaning in the same inspection round, and keep cable entries tidy so dust and moisture are not channelled towards the sensors.
