Encoders-PGcoders With Shaft – Heavy Duty

The shaft incremental encoders are precision measuring instruments to transduce position, distance angle or speed. The PGcoders EN-801P, EN-801H & EN-201 are indigenously manufactured with precision technology. The basic encoder type: EN-801/ EN-901 is incorporated in heavy duty housing type `H’ and `P’. The base mounted encoders are type designated as EN-801H / EN-901H and the flange mounted encoders as EN-801P These incremental encoders register position of the shaft driven by users drive through a heavy-duty coupling. Output is available in form of square pulses incremented (or decremented) step by step in users counter or PLC. Direction can be determined with the help of two trains of pulses running in quadrature. One index pulse is available per rotation for orientation of mechanical position.

Infra-red Sensors & Safety Guards

These invisible light barriers work on emission of infra-red rays which either get interrupted or reflected from the object to be sensed by the sensor. In transmission mode, the emitters & detectors are placed in opposed mode in which the object interrupts the beam or else. In reflection mode, it gets reflected to give an ON/OFF output signal. They are available in different forms (tubular & box type) for sensing distances upto 12M in transmission mode & 1.5M in reflective mode. Infra-red safety guards Series GA-- form an invisible curtain which if interrupted by finger or hand gives a signal to shut off the drive.
