Miniature Belt Alignment Switches (Stainless Steel)
The HLM-SS-CBA Miniature Belt Alignment Switch comes with a stainless-steel roller and is enclosed in a 316 stainless steel body.
These switches are specifically designed for narrow conveyor sections to prevent belt drift caused by unintended movements. They can be installed at appropriate intervals along the conveyor to ensure that if the belt position deviates, the roller arm of the switch will move to a predetermined position and trigger a control circuit.
The switch’s roller is positioned near the conveyor belt’s running edge so that when the roller and arm are deflected, the internal contacts of the switch are activated or “tripped.” The switch allows for the adjustment of the tripping angles and the necessary activation torque.
All switches conform to European Standard IEC 60947-5-1 and provide positively operated contacts at the point of tripping. They can be used to satisfy the requirements of EN 620 about conveyor control hazards caused by shifting of the belt position during running. They are available in different roller diameters to provide heavy duty performance and long life.
Product range features:
- Heavy duty 316 Stainless Steel Construction
- Positive opening NC safety contact to EN60947-5-1
- Slow break or snap action contacts
- High mechanical life over 500,000 cycles
- Industry standard mounting to EN50041

Mini Belt Alignment Switch – Stainless Steel, 22mm Diameter with 70mm Length Roller (HLM-SS-CBA)
IDEM’s stainless steel mini conveyor belt alignment switches are designed for use on the running edge of conveyor belts. They are suitable for both indoor and outdoor use and can withstand extreme weather conditions. Unlike the larger belt alignment switches, the mini duty versions only feature a stop signal.
