Part-Ejection Scanners |

FEATURES - Scans up to 3600 parts per minute - Detects parts as small as 0.2" (5 mm) in diameter - Operating range up to 48" (1.2 m) - Optional counters, CS (control signal), OS (out-put signal), and optional power supply. The part-ejection scanner creates a two-dimensional sensing field. As parts are ejected by forming and stamping machines, they can be detected as they pass through this field. By verifying that each object has been ejected, machine jams can be prevented and costly damage to expensive tools can be avoided. The part-ejection scanner output may be used to send a stop signal to the automated machine should a part not pass through the scanning field as expected. Objects as large as the scanning fields or as small as .02 inches (5 mm) in diameter can be detected at rates up to 3600 parts per minute. Three models with scanning heights of 4, 8, and 13 inches (102, 203, and 330 mm) are available. The basic part-ejection scanner is comprised of a self-contained, infrared transmitter bar and a corresponding receiver bar, cables, and a shock-mount kit. On the receiver bar, the user may select either the light-operate or dark-operate mode using a 3/4-turn potentiometer. The light-operate mode causes the outputs to turn on when no object is detected; the dark-operate mode causes the outputs to turn on when an object is detected. Both transmitter and receiver bars operate at 24 V DC, and the receiver simultaneously provides two open collector transistor outputs (NPN sinking and PNP sourcing) for user connections. Aligning a part-ejection scanner for proper operation is easy. Simply parallel the bars and aim the transmitter at the receiver until the indicator glows. A transmitter power control is adjusted until an LED on the receiver glows. Each bar requires a cable with a quick disconnect on one end. The transmitter and receiver 16 1/2' quick-disconnect cables have two and four wires respectively. These cables may be attached to an existing power supply, or please consult the factory if a power supply is needed. |
