Glossary
Term
Definition
Body
Cylindrical aluminum housing and air pressure chamber. An interface plate to the
user’s robot is usually attached here.
Cam
A hardened steel ring mounted inside the cover on which the hardened steel ball
segments mounted to the stem are nested.
Collision Sensing Switch
A switch that changes state to an open circuit when a crash is detected. It is
mounted in a threaded hole in the side of the body under the connector block. It is
a normally open, PNP or NPN metal sensing proximity switch. It appears closed
in the working (reset) position since it is sensing a steel target. The steel target
moves out of range in the event of a crash.
Collision
The accidental impact between the end of arm tooling and some
obstruction in its path.
Cover Plate
Disk‑shaped aluminum cover for Collision Sensor body.
Crash
The result of a disturbance that displaces the Collision Sensor components from
their standard, working position.
Interface Plate
Optional component used to adapt the Collision Sensor body or stem to the
user’s robot or tooling.
Piston
The component which, together with the Body, creates a pressure chamber.
Varying the pressure in this chamber varies the load required to move the piston.
Reset
The ability of the Collision Sensor to return to its working position when a
disturbing force or displacement is removed.
Stem
Round tapered post containing tapped holes and a dowel pin hole. An interface
plate to the user’s tooling is usually attached here.
Switch Target
A steel block mounted on top of the piston, the position of which is sensed by the
Collision Sensing switch.
