- 2342727-4 : 5.X Cradle encoder. This part replaces the 2342727-3 and 2342727-2 This is an absolute position encoder with no pot. See long description for details Displaying Change-Up Data: Part "2342727-2" and "2342727-3" changed to 2342727-4 Part #: 2342727-4 Part Type: GP CONSUMABLES Part Weight: 0.00 LBR Repairable: No Returnable: No Hazardous Material: N Description: FRABA OCD H-Power String Encoder FRU: Yes Status: Orderable Comments: Added by ecr: 2020264. Please continue to use stock of 2342727-3, until depleted. -3 and -4 are mfg alts of one another. ms13452 Revised per to Asset confirmation Comments: Added per ECR2011883 to replaced the 2342727-2 The 5.x table design incorporates Absolute encoders used for cradle and elevation, instead of incremental encoders. The absolute encoder has the capability to generate a unique binary 'word' for each encoder shaft position, allowing the encoder to provide positional information instantly upon power-up, unlike incremental encoders. Therefore, potentiometers are NOT needed for cradle or elevation encoder circuits.
