Seat belt sensor switch

Based on contactless (non-contact / wear-free) hall effect working principle, we provide custom reed switches sensor detection assemblies that afford superior performance detecting when a seat belt tongue has been engaged even under extreme environments and challenging conditions such as dust, dirt, high vibration, extreme temperatures, etc.

Only two wires and no external magnets or moving parts are required, thus saving space, time, cost and set-up operations for seat belt buckle reminder sensing.

Fully sealed and with virtually unlimited life (maintenance free), the sensor will detect when the buckle metal part is instered and will reliably change its state from open to closed or viceversa. This information is used to trigger the airbag, the Not-On warning light and to turn the car off in some car brands.

Full customisation is available including electrical and mechanical characteristics, output, size and integrated connectors.

Other seat positions sensors and security-related airbag controls have been developed by Piher.

With over 40 years serving to most of the car brands, the pursuit of the most cost-effective total solution for your needs is firmly embedded in our business philosophy, so whatever your requirements may be, be sure that Piher will deliver.

Piher´s advantage

• The technology used for this kind of sensors, Reed Switch or Hall Effect, provides superior performance detection even under extreme and challenging environment conditions such as dust, dirt, high vibration or temperature.
• Simple dual module design with only two wires with no external magnets or moving parts required, thus saving space, cost and set-up operations.
• Fully sealed for harsh environments without mechanical wear between both modules and customizable lifetime specifications.
