Sensors are used to control positions and speed of the actuators used in automation designs. In order to achieve proper functional sensitivity from the sensors, placement of the sensors become important.

Sensor types and mounting methods

(1) Sensor types and definition

Definition of a sensor is as follows.

Sensors must be placed properly to detect the physical occurrences (presence of objects, speed, pressure variations, etc.) accurately.

(2) Position detection sensor types and points on location adjustments.

　Position detection sensors are following types.

(3) Position detection sensor mounting

	・	For a single axis linear motion system, an end-of-travel limit switch at each stroke end, and a home position limit switch will be used.
	・	Use a [1] Sensor rail and [2] Bar nuts to mount the sensors. See [Fig. 1] and [Photo 1] for usage examples.
	・	[Photo 2] shows an arrangement of position sensors/sensor rails/bar nuts for a 2-axis XY table.
