GEAR TEETH IDEAL FOR TACHOMETER, COUNTER AND CONTROL INPUT DESCRIPTION PSAC APPLICATION The PSAC offers a NPN Open Collector output that is compatible with most PSAC application depends on the size, material, and spacing of the targets Red Lion Controls Motion Monitors, Counters, and Controls. This sensor has a being sensed and the sensing distance that can be maintained. The maximum maximum sensing distance of 0.059 (1.5 mm) and can detect ferrous and non- sensing distance is defined as that distance where the sensor is just close enough ferrous metal targets from zero speed to 5 KHz. to detect a ferrous target whose diameter is equal to or greater than the sensor The 0.25 diameter pole piece is epoxy encapsulated in a stainless steel case diameter. For the PSAC, the internally potted sensor diameter is 0.25 . In an measuring 0.75 Dia. x 3.5 L and is supplied with a 10, 25 or 50 ft., 3-wire, actual application the sensing distance should be between 50-70% of the cable. Overall dimensions, including the neoprene strain-relief boot are 0.90 maximum to assure reliable detection. For target sizes smaller than the 0.25 Dia. x 4.5 L. Operating temperature range is -25 to +70 C. sensor diameter, the maximum sensing distance can be estimated from the curve in Fig. 2. A further reduction factor must also be applied if the target material is a non-ferrous metal as shown in Fig. 3.
