Magnetic Proximity Sensors Specifications

Help with Magnetic Proximity Sensors specifications:

Specifications

	Operating Distance		Range of distance measurement, or maximum distance measured.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Repeatability		'Repeatability' is a measure of precision. It is the difference in measurements taken on the same device, under the same conditions.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Operating Temperature		The temperature range over which the device must operate.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Electrical

	Power Requirements
	Your choices are...
	AC Powered		The sensor requires an AC voltage.
	DC Powered		The sensor requires a DC voltage.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Output
	Your choices are...
	Voltage		Output voltage is a simple (usually linear) function of the measurement.
	Current		Often called a transmitter. A current is imposed on the output circuit proportional to the measurement. Feedback is used to provide the appropriate current regardless of line noise, impedance, etc. Useful when sending signals long distances.
	Frequency		The output signal is encoded via amplitude modulation (AM), frequency modulation (FM), or some other modulation scheme, but the signal is still analog in nature.
	Resistance		An output consisting of a simple change in resistance is typically for a magnetoresistive device.
	Switched / Alarm		An "output" of a change in state of switches or alarms
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Load
	Your choices are...
	AC Load		Output is an alternating current switched value.
	DC Load		Output is a direct current switched value.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	DC Load
	Your choices are...
	2-Wire		2-Wire DC circuitry typically includes a diode bridge in series with the sensor, allowing functionality either as NPN or PNP in a DC circuit.  Acceptable values of leakage current must be evaluated in this type of circuit.
	3-Wire NPN		Transistor output that switches the common or negative voltage to the load; the load is connected between the sensor output and positive voltage supply; also referred to as sinking type.
	3-Wire PNP		Transistor output that switches the positive voltage to the load; the load is connected between the sensor output and the voltage supply common or negative; also referred to as sourcing type.
	4-Wire NPN		Transistor output that switches the common or negative voltage to the load; the load is connected between the sensor output and positive voltage supply; also referred to as sinking type.
	4-Wire PNP		Transistor output that switches the positive voltage to the load; the load is connected between the sensor output and the voltage supply common or negative; also referred to as sourcing type.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Switch Type
	Your choices are...
	Normally Open		Switch is 'open' until an object is detected.
	Normally Closed		Switch is 'closed' until an object is detected.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Interface
	Your choices are...
	Serial		A standard digital output protocol (serial) such as RS232, etc.
	Parallel		A standard digital output protocol (parallel) such as IEEE488, etc.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Body Shape

	Body
	Your choices are...
	Cylindrical		The shape of the potentiometer body is shaped like a cylinder/barrel.
	Rectangular		The shape of the potentiometer body is square or rectangular.
	Ring		A round or "doughnut" shaped sensor, where object passes through center of ring.
	Slot		Designed to detect the presence of a vane or tab as it passes through a sensing slot, or "U" channel.
	Other		The body shape is other/specialty.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Threaded Barrel
	Your choices are...
	Threaded Barrel		Body exterior is threaded; often comes with mating nuts for panel mounting.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.
