The HEJ 70 48 50 actuator combines a torque-dense motor, planetary gearbox, 14-bit absolute encoder, and EtherCAT management electronics right into a sealed, IP67-rated package deal. It delivers a peak torque of ±50 Nm and a most joint velocity of 28 rad/s, with efficiencies as much as 74% at 12 Nm and 26 rad/s.
Toronto, Canada – August 8, 2025 – Electromate Inc., Canada’s unique distributor of maxon precision mechatronic elements, publicizes the discharge of the HEJ 70 Excessive-Effectivity Joint actuator. This compact, absolutely built-in robotic joint actuator is engineered to fulfill the demanding efficiency wants of cell and manipulation robots.
Product Overview
The HEJ 70 48 50 actuator combines a torque-dense motor, planetary gearbox, 14-bit absolute encoder, and EtherCAT management electronics right into a sealed, IP67-rated package deal. It delivers a peak torque of ±50 Nm and a most joint velocity of 28 rad/s, with efficiencies as much as 74% at 12 Nm and 26 rad/s. The actuator’s compact design (1.05 kg) and excessive efficiency make it appropriate for light-weight robotic functions.
