There are two main OEM (original equipment manufacturer) product categories available to manufacturers: the Polar Contact Heart Rate System and Polar Wireless Heart Rate System. Here’s what they do:

The Polar Contact Heart Rate (HR) System is a complete HR system for all applications where accurate and convenient heart rate measurement is needed. The Polar Contact HR System utilizes advanced digital technologies to obtain heart rate quickly and accurately from hand sensors and Polar transmitters. In addition, Polar’s exclusive and unique dual mode provides hands-free HR measurement through the wireless receiver integrated directly on the board.
The Polar Wireless system consists of a Polar Heart Rate receiver and Polar Heart Rate transmitter. Together they allow seamless integration of heart rate technology into your training equipment. What’s more, both can be programmed to provide coded transmission/receiving which will eliminate crosstalk between heart rate devices when equipment is placed too close together.
