935 optical isolator thorlans6/5/2023 ![]() This industrial digital optical isolator can also be used with any other PoKeys device such as PoKeys57E, PoKeys57U or any other microcontroller since it effectively isolates up to 16 inputs with LED indication. That said, you can still use any other native PoKeys pin for limit input. Axis 1 can only use dedicated limit+, home and limit- pins for axis 1 and not from any other axis. It is also important to state that the limit and home pins can not be interchanged between axis. Theoutput was then separated from the pump using a di-chroic mirror at 45° that has a reflection>98at 2.9m.An optical isolator (Thorlabs) based on Faraday rotationset the unidirectional. It is recommended to use the PoOptoIN with PoKeys57CNC when limit and home switch cables are longer. With the PoOptoIN limit – and home switches are optically isolated form the environment and therefore more imune to interefence and EMC problems. Please see the Isolator Tutorial tab for an explanation of the operating principles of a Faraday isolator. If it is used with PoKeys57CNC, it can be directly connected to Limit/Home IDC connector. Optical isolators, also known as Faraday isolators, are magneto-optic devices that preferentially transmit light in the forward direction while absorbing or displacing light propagating in the reverse direction (see the schematic below). Both optical isolators can also be used with our precision PNP homing sensor or NPN homing sensor. We also offer smaller digital optical isolator for use with the native PoKeys pins – adapter PNPN. The PNP in NPN sensors can be connected to the PoOptoIN to isolate them from digital circuitry. A limited number of contributed talks will be offered in an asynchronous format. The power supply connection is not mandatory for the operation of the PoOptoIN! The Optica Laser Congress will be presented with Frontiers in Optics + Laser Science as an in-person meeting. ![]() Power supply for the PoOptoIN is only for signal LED-s that indicate the status of each pin (input). More details for IOT-5-670-VLP can be seen below. The outputs are open collector type so pull up resistor is needed to ensure the stable state of the digital pin if the board is used directly with the microcontroller.

The IOT-5-670-VLP from Thorlabs Inc is a Fiber Optic Isolator with Isolation 55 - 57 dB, Optical Power 1.7 W, Wavelength 640 - 700 nm. All the input channels are isolated from each other. It accepts 5-24V on input connector that is optically isolated from the output IDC connector. Thorlabs in-house manufacturing service has over 25 years of experience and can deliver a free-space isolator tuned to your center wavelength from 244 nm to 4.55 µm. ![]() PoOptoIn is 16-channel industrial digital optical isolator. This 650 nm low power free space optical isolator is packaged in a compact cylindrically shaped magneto-optic device with a base plate for ease of mounting into. ![]()
