Looking for cobot safety solutions?
Verify your PFL force limits →ISO/TS 15066 gets cited like scripture and applied like superstition. The body-region force limits in Annex A are the most misread numbers in cobot integration. 140 N at the chest is the quasi-static limit: the ceiling for clamping, not for every contact event. Transient contact allows roughly twice that. Half the cobot deployments we see apply the lower quasi-static number everywhere, which is over-conservative on impact scenarios and gets the risk assessment's own logic backwards: separation monitoring is an ISO 10218 mechanism, not a force limit.
The articles in this section work through the standards the way you'd apply them on a line. Risk assessments built to survive audit. Validation tests designed around the contact scenarios in your cell. The methodology is drawn from production cobot deployments where the safety case had to hold up to a TÜV reviewer with hard questions.
If you need a measurement system that holds up to that kind of review, our CoboSafe pressure measurement platform was built for exactly this work. GTE manufactures it in Germany. Inmotion sells and supports it in the US.
