Page 5: Preliminary Information
Preliminary information This guide is designed to provide the most complete and exhaustive information the operator needs to correctly and safely install and operate the SMA5 series absolute linear encoder. SMA5 is designed to measure displacements in industrial machines and automation systems. The measurement system includes a magnetic tape and a magnetic sensor with conversion electronics. -

Information is listed in the delivery document too. Please always quote the order code and the serial number when reaching Lika Electronic for purchasing spare parts or needing assistance. For any information on the technical characteristics of the product refer to the technical datasheet. -
Page 8: Mounting Instructions
SMA5 3 – Mounting instructions WARNING Installation has to be carried out by qualified personnel only, with power supply disconnected and mechanical parts compulsorily in stop. 3.1 Overall dimensions 3.2 Magnetic tape The sensor has to be paired with the MTA5 type magnetic scale only. For detailed information on the MTA5 type scale and how to mount it refer to the specific technical documentation. -
Page 9: Mounting The Sensor
SMA5 3.3 Mounting the sensor Figure 1 Make sure the mechanical installation complies with the system requirements concerning distance, planarity and parallelism between the sensor and the scale. Avoid contact between the parts. Sensor is fixed by means of two M5 25 mm min. - Page 10 SMA5 Figure 2 WARNING After having installed the sensor on the magnetic scale a zero setting operation is compulsorily required. The zero setting operation is further required every time either the sensor or the scale is replaced. For further information refer to page 12.

Page 14: Ssi Interface
SMA5 5 - SSI interface Order code: SMA5-GA-… 5.1 SSI (Synchronous Serial Interface) Synchronous Serial SSI (the acronym for Interface) is a synchronous point-to-point serial interface engineered unidirectional data transmission between one Master and one Slave. Developed in the first eighties, it is based on the RS- 422 serial standard. -

SMA5 transmission. The cycle ends at the last rising edge of the clock signal (3). This means that up to n + 1 rising edges of the clock signals are required for each data word transmission (where n is the bit resolution); for instance, a 13-bit encoder needs 14 clock edges. -
Page 16: Recommended Transmission Rates
SMA5 WARNING The position value issued by the sensor is expressed in pulses; to convert the pulses into a metric measuring unit you must multiply the number of detected pulses by the resolution. EXAMPLE SMA5-GA-5-… resolution = 5 µm = 0.005 mm detected pulses = 123 position value = 123 * 5 = 615 µm = 0.615 mm 5.3 Recommended transmission rates... -
