Madison Company's P Series proximity sensors manufacturers use reed switch-based technology, which offers reliability of up to 5 million cycles. Offered in both plastic and metal housings, these proximity sensors are interchangeable with existing sensors of similar characteristics or can be designed specifically for individual application needs.

These noncontact sensors are available with single pole double throw switches (Form C), or Form A and B. They offer a variety of ways to sense the relative position of specific machine elements requiring continuous monitoring. Several different fabrication materials can be used. Materials are selected based on the application environment. The standard operating temperature range is from -40°C to 125°C (-40° to 257°F).

Sensors can be ordered in sets containing the sensor, the supplier of actuator and hardware, or the components can be ordered separately. These cost-effective sensors are offered in standard designs and engineered designs with various actuation points.
