Position Detector 3.2 WIDENT/P for 8 positions (NC contact) Position detector for detection of eight different codes with eight outputs (NC contact). 3.3 WIDENT/P for 15 positions (Binary code) Position detector for detection of 15 different codes with four binary coded position outputs and one strobe output (NO contact). Other versions of the WIDENT/P position detector on request. 3.4 Application example with 8 positions Conventional roller shutter control: Limit switches, which are operated by cams attached to the moving part of the machine, are frequently used for easy position detection of linear or rotary movements in machines and systems. In this case it is only possible for the machine control system to assign the limit switch signal definitely to the position if a separate limit switch is used for each position. Roller shutter Rolltor door By using transponder-based WIDENT/P sensors, which e.g. in safety engineering are known as non-contact SIDENT safety switches, it is possible to detect several different positions with only one sensor. A further advantage in this case is insensitivity to dirt, maladjustment and manipulation and the avoidance of components susceptible to wear. Transponder-based actuating elements are attached to the moving part of the machine instead of the operating cams with the result that the WIDENT/P, which is mounted on the stationary machine part, can detect the actuating elements and read their intrinsic information as they move past. A specific code is assigned to each of the actuating elements so that the WIDENT/P’s position detector can detect which actuating element is currently within its reading range based on the code. An associated output switching signal which can be processed in the machine control system is generated in the WIDENT/P in line with the information read out. Innovative roller shutter control: Code “1” Code “2” Code “3” This principle can also be used, for example, to control a roller shutter as shown in the diagram above. Actuating Betätigungselements elemente All the electronics of this position detector are accommodated in a sensor housing. Connection is made by a 12-pin connector. There are four green and two yellow LED’s as position indicators. A further green LED serves as a status indicator.

Response range The following values are applicable for parallel and central alignment of the sensing faces of sensor and actuating element. If the sensing faces are inclined towards each other, this results in deviations from the values mentioned by around ± 10 % at an angle of inclination up to 30°.
