Torque limiter takes proximity sensor
onboard
A new torque limiter disconnects the main power source from its downstream components in the event of a torque overload or product jam, to protect the gear reducer, machine and product.

Roller pinion system is alternative to ballscrew
The RPS precision roller pinion system converts rotary motion into very precise, backlash-free linear motion, while quietly operating at high speeds over long distances.
Calliper brake will not fade with time
Nexen Group is introducing its new Air Champ VC500 calliper brake that gives zero reduction in brake torque over the life of the friction facings due the rear amplifier linkage design.
When an overload occurs, the proximity sensor next or adjacent to a dowel pin embedded in the torque limiter's air chamber sends a signal to the pneumatic, directional control valve to exhaust air from the air chamber, which disconnects and protects the system.
The Turck proximity sensor is mounted within the envelop of the torque limiter length, providing easier mounting and ensures proper torque transmission to extend product life.
The torque limiter's hard-chrome detent interface decreases drive-ring wear when the balls are pressed against the face during the jog-to-position engagement function.
The air chamber is sealed with O-rings and backup rings.
The backup rings prevent seal extrusion into the diametric gap between the piston and cylinder to extend seal life.
The product's remote trip-torque setting with air regulator eliminates the need for manual torque adjustments as seen with mechanical torque limiters.
In semi-open units, Model sizes TL10A to TL80A, a seal keeps contaminates out of the ball and detent area.
Totally enclosed units are nickel-plated and sealed to keep contaminants out of the ball, detent, and spline area, which makes them ideal on machines requiring wash down or where liquid products could splash on the unit.
Nexen's torque limiters are used in the food processing, material handling, newspaper, bottling, and packaging industries.
