ELS on a SOuth Bend 9

mike allen All Messages By This Member #2034 hey folk's has anyone? done this ELS on a South Bend 9 lathe ? I'm lookin to see some pics of encoder mounting if anyone has any thanks animal

Been working without issues for probably since about 2008. ? ? This is on a different lathe.? Again easy to do. ? toggle quoted message Show quoted text > -----Original Message----- > From: [email protected] [mailto:[email protected]] On Behalf > Of mike allen > Sent: May 6, 2025 6:39 PM > To: [email protected] > Subject: [digitalhobbyist] ELS on a SOuth Bend 9 > > hey folk's has anyone? done this ELS on a South Bend 9 lathe ? > > I'm lookin to see some pics of encoder mounting if anyone has any > > thanks > > animal > > > > ?
mike allen All Messages By This Member #2036 开云体育 we were gettin a ton of bounce with the sensor I originally picked . but I totally missed the part where i needed to use a pull down resistor . so maybe it? get's better with the resistor . ? thanks animal On 5/6/25 11:09 PM, John Dammeyer wrote: toggle quoted message Show quoted text Here's a photo of my South Bend Heavy 10L with a magnet in the bearing clamp hole and a hall sensor to pick up the magnet.?

John Dammeyer All Messages By This Member #2037 开云体育 There’s no specification on those devices as to speed.? I would not use them as spindle sensors. ? toggle quoted message Show quoted text From: [email protected] [mailto:[email protected]] On Behalf Of mike allen Sent: May 6, 2025 11:38 PM To: [email protected] Subject: Re: [digitalhobbyist] ELS on a SOuth Bend 9 ? we were gettin a ton of bounce with the sensor I originally picked . but I totally missed the part where i needed to use a pull down resistor . so maybe it? get's better with the resistor . ? thanks animal
BuffaloJohn All Messages By This Member #2042 You don't need a pull down for that hall effect sensor, you need a pull up. The output is the collector of an NPN transistor, so open collector. There is a datasheet: Brown is supply to sensor.? Black is Open Collector output (if you don't put a pullup, it will only float up) Blue is sensor ground page 3 shows the schematic you would use, including a level shifter made of resistors to keep the output voltage in the range the processor needs. You can adjust the resistors to make the range be 0..3.1v if that is what you need. toggle quoted message Show quoted text On Tue, May 6, 2025 at 11:37?PM mike allen via <animal=[email protected]> wrote: we were gettin a ton of bounce with the sensor I originally picked . but I totally missed the part where i needed to use a pull down resistor . so maybe it? get's better with the resistor . ? thanks animal On 5/6/25 11:09 PM, John Dammeyer wrote: Here's a photo of my South Bend Heavy 10L with a magnet in the bearing clamp hole and a hall sensor to pick up the magnet.?
