Series R04

Miniature Force Sensors

Extremely compact force measurement sensors for tensile and compressive loads in applications with limited space. The Series R04 is available in capacities from 0.25 to 100 lbF (1 to 500 N). Every capacity has the same miniature dimensions. The sensors feature outstanding mechanical overload protection and threaded holes on two sides for the mounting of attachments or implements.

Requires a Mark-10 indicator, available separately.

Features
