406) Stacking saddle or arch

An element of the leg of a container that engages the container wall below to ensure safe stacking.

407) Strip base

A base of an industrial metal container utilizing a combination stacking saddle and bearing plate.

408) Yield strength

The guaranteed minimum yield point stress of the material as specified by the steel supplier.

409) Gage

A standard measure for sheet steel thickness or wire diameter.

410) Mesh size

The center-to -center spacing of the wire elements on a wire mesh container. For example, a 2x2 = wires on two inch centers in both directions.

411) Active face

The surface of an inductive proximity sensor where a high frequency electromagnetic field emerges, although there is no direct magnetic field occurring.

412) Collision prevention

The use of sensors to detect the presence of objects and, through the use of integrated controls, prevent a collision between two objects from occurring.

413) Convergent beam

Another name for fixed focus sensing where the photoelectric sensor will only detect objects at a fixed distance from the sensor.

414) Data transmission

The use of sensors to transmit data via pulse-modulated light beam systems typically from host stations to mobile carriers such as AGV's or stacker cranes.

415) Dispersion angle

The degree of the angle of light.

416) Echo

The time elapsed between pulse emission and reception that is used to determine target position in an ultrasonic proximity sensor.

417) Effective beam

The usable beam diameter in photoelectric transmitted beam sensing which equals the lens diameter of the light source and receiver.

418) Excess gain

The point at which just enough light intensity is present to trigger a photoelectric sensor given the usable area of the lens,  For example, an excess gain of two would mean that just enough light intensity is present to trigger a sensor with 50% of the lens obscured with contaminants.

419) First surface protection

The ability of polarized retro-reflective photoelectric sensors to eliminate false operation as a result of shiny objects.

420) Fork or loop lever

A lever type limit switch that uses maintained contact and two wheels rotating around the ends of a "horseshoe" that pivots as the actuator to detect an object(s) moving in the forward and reverse direction.
