Developed to meet a wide range of feedback applications, Newall's Absolute linear encoders provide a true absolute position immediately upon power-up. The encoder does not use batteries or static memory to retain the positional data. True position can be reacquired once power is applied, regardless of duration or power-off movements.

The encoder is ideally suited for linear motor and other high velocity measurement applications including CNC/PLC feedback, pick and place machines, automotive transfer lines, packaging machines, PC-based systems and more.

RS232	SHG-A2	RS232 serial communication is typically used to interface with PC "COM" ports. This EIA standard allows for data transmission from one transmitter to one receiver at data rates up to 20K bits/second and distances up to 15m at the maximum data rate. A serial to USB converter is available to allow interface via a USB port. SHG-A2 - RS232 Protocol (241k)
RS485	SHG-A4	This EIA standard meets the requirement of a multi-point communication network, which as standard specifies up to 32 drivers and 32 receivers on a single two-wire bus. A key feature is the ability to address individual devices. This model can be ordered with unique address tags to facilitate multiple devices on the RS485 bus. SHG-A4 - RS485 Protocol (241k)
SSI		SSI (Synchronous Serial Interface) is a patented absolute encoder protocol. A clock signal is provided by the control and facilitates transfer of absolute position on the data lines. There are several variations of SSI currently available.
	SHG-AB	SSI Binary | Data Bits: 24 | Parity: None SHG-AG, SHG-AB - SSI Protocol (188k)
	SHG-AG	SSI Gray Code | Data Bits: 24 | Parity: None SHG-AG, SHG-AB - SSI Protocol (188k)
	SHG-AS	SSI Gray Code w/TTL incremental signals (typically used for Siemens controls) Data Bits: 24 | Parity: Even. SHG-AS - SSI w/Parity Quad Protocol (226k)
Fanuc Serial	SHG-AF	This is a proprietary absolute encoder protocol. It is used exclusively with Fanuc CNC products that require absolute positional feedback.  SHG-AF - Fanuc Protocol (305k)

Quick and Easy Installation
The design of these linear encoders allow installment in almost any position, unlike glass-scale linear encoders, which usually need to be installed with the lip seal facing downwards to prevent contamination. Self-aligning fixing brackets allow virtually effortless scale mounting, needing only a single hole for each set of brackets.
