| ||
| Measurement Range | 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. | ||
| |||
| Accuracy | Accuracy describes the percent deviation from the actual/real value of the measurement. | ||
| 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. | ||
| |||
| Linearity | Linearity is the maximum deviation from direct proportionality between the distance measured and the output distance over the measuring range. | ||
| 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. | ||

String Potentiometer Technology

|
|
| ||
| Your choices are... | |||
| Potentiometer | A potentiometer cable extension position sensor is made of a flexible cable and spring-loaded spool and is used to produce a change in the resistance output. This output is directly related to the distance of the target from the sensor. | ||
| Optical Encoder | An optical encoder converts the linear motion of the sensor shaft into an output signal. | ||
| 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. | ||

|
| ||
| 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 over 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, 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. | ||
| |||
| 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 | A potentiometer body is shaped like a cylinder/barrel. | ||
| Rectangular | A potentiometer body is square or rectangular. | ||
| Ring | A round or "doughnut"-shaped sensor, in which an 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. | ||
