Not ESD Sensitive

Reed based proximity sensors are not susceptible to damage from electrostatic discharge

Pick-and-Place Capable

Tape and reel packaging, surface mount contacts, overmolding and a robust design make our switches great for pick and place applications

Full lot traceability

Raw materials are tracked from start to finish of production

Hermetically sealed tungsten contacts

Ideal for high-voltage medical equipment

No electrical power required

Our sensors do not draw power to operate and the only power constraint is the battery life of implantable devices
