The smallest high precision absolute encoder from Netzer

MCP says that the Electric Encoder™ is holistic and that its output reading is the averaged outcome of the whole area of the rotor, a feature which makes it forgiving of mounting tolerances and mechanical wander for example. Its non-contact technology relies on an interaction between the measured displacement and a space/ time modulated electric field. MCP states that the absence of components such as ball bearings, flexible couplers, glass disc, light sources and detectors (along with very low power consumption) makes the Electric Encoder™ virtually failure-free.

MCP’s DS-16 absolute encoder from Netzer is claimed to be the world’s smallest precision encoder, with a diameter of Ø16mm and low profile of 8mm in length. It is said to offer high performance, be a strong design and has a 16-bit resolution. It is DC operated and semi-modular in that its rotor and stator are separate, with the stator securely housing the rotor. MCP s says that accuracy can reach 0.035° and that it supports BiSS-C & SSi absolute encoder feedback, which is compatible with all MCP’s flagship servo drives.

The DS-16 absolute encoder was originally developed for harsh environments and critical applications and is designed to operate between -40°Celsius up to +85°Celsius with a high tolerance to shock, EMI, RFI and magnetic fields. This, says MCP, makes it suitable in a broad range of applications, including defence, homeland security, aerospace, and medical and industrial automation such as smaller robotic arm joints, accurate miniature camera gimbles etc.
