Original Press Release:

Low-Cost Thin Spring Engaged (Power Off) Brake from SEPAC is Up to 70% Thinner for OEM Applications

ELMIRA, NY – SEPAC designed the Thin Spring Engaged Brake (TSEB) to provide OEMs with a thin body high-performance/low-cost spring engaged power off brake. The TSEB is 60 – 70% thinner and up to 20% less expensive than conventional servomotor type high-performance brakes. The TSEB offers reversible mounting – with the shaft extending past the brake or within the brake body for the shortest, thinnest package. The friction disc/rotor and hub are manufactured from lightweight metal, allowing for lower inertia. A splined hub for shaft connections typically provides less than 1.5° backlash.

The TSEB is ideal for a wide range of OEM applications, including: servo motors/systems, medical apparatus, robotics and imaging equipment, material handling, semiconductors (wafer handling equipment), energy-related (wind, petroleum, etc.) actuators, and security-related actuators for doors, gates and curtains.

Key features and benefits of the TSEB include:

• Reversible mounting

• Low backlash (less than 1.5°)

• Low inertia

• Cost effective: 10 - 20% lower than competitive products

• RoHS compliant

• UL Class F insulated coil system
