If dirt, dust, grease, humidity and other contaminants that commonly impair the performance of optical encoders are an application concern, magnetic rotary position sensors are possible alternative. With a total system cost normally far lower than the cost of an equivalent optical encoder or resolver, ams new version of its 47 series of magnetic rotary […]

Encoders Fit into Tight Spaces
Motor manufacturers looking for more design flexibility should appreciate thinner encoders. To satisfy these customers, HEIDENHAIN has two new rotary encoders. The ECI 1118 rotary encoder has a thickness of only 10 mm and a diameter just less than 37 mm. The absolute encoder offers a resolution of 18 bits and an accuracy of ±120”. […]
Magnetic Absolute Rotary Encoders Achieve Accuracies of up to 0.1°
Targeting tough ambient conditions such as dirt, vibrations, or extreme temperatures, Pepperl+Fuchs designed its ENA58IL and ENA36IL magnetic absolute rotary encoders to deliver high precision and resolution as well as an extremely durable, compact design. To achieve this, the design adds a Wiegand sensor to a two-axis Hall sensor. The Halls sensor measures changes in […]
Small Profile Linear Encoder Includes Advanced Features
With a size of only 36mm x 13.5mm x 14.8mm, RSF Elektronik’s MS 15 optical kit linear encoder could have the industry’s smallest mechanical profile – it also boasts several advanced features. The kit encoder provides a 40-micron grating pitch on an 8-mm wide steel tape carrier that has a double-stick backing for mounting directly […]
Absolute Encoders Fit in Cramped Application Spaces
SICK’s AHS/AHM36 absolute encoders are only 36 mm in diameter. The single-turn and multi-turn magnetic encoders have a 270° rotating M12 connector or cable outlet for easier installation in limited spaces. Available products include: face mount flange, servo flange and blind hollow shaft versions each with five different shaft diameters and various adapters. With either […]
Inherently safe fiber optic estop and u-beam sensors
MICRONOR introduces two new inherently safe, fiber optic signaling products for the industrial automation, robotic and medical markets. The MR380 series Fiber Optic Emergency Stop offers ESTOP Functional Safety compliance with SIL1 rating. The MR382 series Fiber Optic U-Beam Sensor is a general purpose photo interruption/slot sensor. The products consist of a passive optical Sensor […]
Easy-to-use magnetic position sensor
ams AG (SIX: AMS), a provider of high performance analog ICs and sensors, introduced the AS5600,a magnetic rotary position sensor which makes it easier than ever before to replace a traditional potentiometer with a more reliable contactless alternative. To appeal to manufacturers and users of potentiometers, the AS5600 features a ratiometric output, mirroring the output […]
Speed and Position Feedback at Shallow Installation Depth
The new bearingless encoders MIR 10 by Baumer are the products to choose for position and speed feedback in limited installation space. Operating on non-contact magnetic sensing with up to 4096 ppr, the encoders are wearfree and provide virtually unlimited service life.The fully encapsulated magnetic sensor with IP 66 and IP 67 as standard protection […]
Magnetic Position Sensor Provides High Accuracy
With Dynamic Angle Error Compensation (DAEC™), a patent-pending technology developed by ams AG, its new “47 series” position sensors eliminate the measurement error attributable to propagation delay. The 47 series includes the AS5047D, AS5147 and AS5247. Propagation delay (typically 100-200 µs) occurs in traditional magnetic rotary position sensor ICs as they convert raw measurements of […]
Absolute Linear Kit Encoder Targets High Mounting Tolerances and Reliability
If you have purchased and have been satisfied with a sensor, it can be a pleasant surprise when the manufacturer makes a new part that matches the dimensions of the one you have and allows a simple replacement providing an upgrade to the original. That’s exactly what HEIDENHAIN’s did with its LIC 2100 series absolute linear […]
