The L51K13MEL121 uses a large 50mm rubber roller instead of metal or plastic, cushioning the shock and cutting the noise of higher-speed cam or conveyor actuation. On high-cycle bottling, filling, or packaging lines, that softer contact translates directly into a longer switch life than a harder roller would give.

Technical Details
Frequently Asked Questions
Why choose the rubber roller over metal or plastic?
The rubber roller absorbs shock and reduces noise on higher-speed cam or conveyor actuation, extending switch life in high-cycle applications.
What applications suit this switch?
Bottling and filling lines, packaging machinery, and any high-cycle application where noise or shock reduction matters.
Is this suitable for outdoor or washdown installation?
Yes — IP65 rated, protected against dust ingress and low-pressure water jets.
What contact configuration does it give me?
1NO+1NC on a changeable contact block, so you can wire whichever function your circuit needs, or swap the block if requirements change.
Industry Applications
- Higher-speed cam switching — smoother, quieter actuation on fast-cycling equipment
- Conveyor systems — shock and noise reduction on continuous-duty lines
- Bottling, filling & packaging machinery — extended switch life under high-cycle conditions
