Don’t settle for any transducer: incremental SMR5H and absolute SMLA encoders are specifically designed for accurate installation and measurement on arcs and curved surfaces up to 360°.
Following several custom requests, Lika Electronic has developed a specific range of contactless encoders ideally suited for installation on round axes up to 360° & arcs with virtually any diameter.
SMR5H is a quadrature incremental encoder specifically engineered for installation on the inner side of arcs from 176 mm / 7” min. diameter and up. It will be available also for full circumference soon. SMR5H is compact, has a shallow profile (15 mm / 0.59” depth) and, even better, is curved-shaped; this allows it to fit into arcs with constrained and tight mounting space (such as inside a torque motor enclosure) and guarantees quickness and ease of installation. It is contactless and encompasses a proven magnetic technology fully integrated into a rugged and hermetically encapsulated housing with an IP67 protection rating. Thus, it is ideally suited to operate in aggressive industrial environments and provides virtually wear-free and maintenance-free operation under tough conditions, such as when dirt, moisture, oil, vibrations and shocks are present. The sensor generates square wave signals with complementary signals through either Push-Pull (HTL) +10-30Vdc or Line Driver (TTL) +5Vdc output circuits. Resolutions are on request. As an additional advantage, SMR5H is equipped with built-in sensor to provide the Reference signal. Furthermore, it is fitted with integral LEDs to signal power on status and reference sensing. Please note the lateral cable outlet to save space and increase convenience.
When it comes to the highest precision needs on curved surfaces up to 360°, the SMLA absolute encoder is the perfect match. It offers resolutions up to 14 bits over 400 mm / 15.7” measuring length (longer travels available soon). Output circuits can be SSI or BiSS-C and they both provide alarm bits. The magnetic sensing technology allows for non-contact and frictionless measuring principle with no components subject to wear or fatigue. Furthermore, SMLA affords excellent durability under adverse conditions and temperatures (-25°C +85°C, -13°F +185°F) thanks to the encapsulated electronics and its IP68 protection aluminum enclosure. This guarantees reliability over time and longer operating life. Remarkable speeds up to 5,000 rpm and 16 m/s can be achieved.
High performance and resolution enable typical use in industrial applications that need the greatest precision and accuracy such as in fast pick & place robots and delta robots, as well as in 3D printers, but it is suitable also for electronic assembly systems and precision material handling equipment to move highly fragile products. It is effectively used also to measure the rotation of the rollers on folding machines.
Lika Electronic is able to supply all-in-one measuring systems with incremental or absolute encoder and custom curved structures on request.
