| Technology | |||
| Your choices are... | |||
| Capacitive Proximity Sensor | Capacitive proximity sensors detect the presence or proximity of a target using capacitive technology. | ||
| Eddy Current Proximity Sensor | Eddy current proximity sensors and switches detect the proximity or presence of a target by sensing the magnetic fields generated by a reference coil. | ||
| Inductive Proximity Sensor | Inductive proximity sensors detect the presence or absence of an object using a critical distance. | ||
| Hall Effect Proximity Sensor | Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance. | ||
| Magnetic Proximity Sensor | Magnetic proximity sensors include devices that work on inductive, variable reluctance, magnetoresistive or Hall effect principles. These sensors detect the presence or absence of an object using a critical distance. | ||
| Photoelectric Sensors | Photoelectric sensors use emitters and receivers to detect the presence, absence, or distance of target objects. | ||
| Ultrasonic Proximity Sensor | Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component. | ||

| |||
| 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 | ||

| |||
| 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. | ||
