The 5i advanced digital force / torque indicator is designed to work with a wide range of Mark-10 remote force and torque sensors (see below). With exclusive Plug & Test™ technology, all calibration and configuration data is saved within the sensor’s smart connector, not the indicator, allowing for true interchangeability. Sensor password protection prevents use of an unauthorized sensor. In addition, all sensors are fully compatible with the more basic 3i force / torque indicator.
