Stretch sensor

For measurement of small movements

Stretch materials up to 30% without permanently deforming.
On both sides copper clips for mounting the sensor on the product with little resistance loss.

Precise movement measuring by changing resistance in the material
Two types of material, conductive fabric and conductive rubber.

Length sensor can be specified on request.
The sensor doesn’t have any sharp edges so it can be used on skin.
