Industrial Motion & Position Sensors 1% SENSOR LINEAR 100MM

In simple terms, the ThinPot membrane potentiometer is a resistive element, which comprises a conductive resistor, a sealed encasement and a simple wiper assembly. A membrane potentiometer can also function as a voltage divider

Resistance - Standard: 10k Ohms (lengths >300mm = 20k Ohms)-Resistance - Custom: 1k to 100k Ohms-Resistance Tolerance: ±20%-Effective Electrical Travel: 8 to 2000mm-Linearity (Independent): Linear ±1% or ±3% Rotary ±3% or ±5%-Repeatability: No hysteresis, but with any wiper looseness some hysteresis will occur-Power Rating (depending on size, varies with length and temperature): 1 Watt max. @ 25°C, 0.5 Watt recommended-Resolution: Analog output theoretically infinite; affected by variation of contact wiper surface area.-Dielectric Value: No affect @ 500VAC for 1 minute

Sharp Sensor GP2Y0A21YK0F

GP2Y0A21YK0F is a distance measuring sensor unit,composed of an integrated combination of PSD (position sensitive detector) , IRED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used asa proximity sensor
