Rotary sensors cut the cost of noncontact controls
The SV21 series of rotary position sensors claims a breakthrough in the price/performance barrier for these increasingly popular noncontact devices.
The SV21 series of rotary position sensors from Murata claims a breakthrough in the price/performance barrier for these increasingly popular noncontact devices. To date, they have been significantly more expensive than traditional contact types, but with the SV21 series, Murata has succeeded in delivering a low cost noncontact sensor without compromising on performance or reliability. Murata's SV21 series offers wide rotational angle effective up to 200 degrees, considerably greater than traditional devices.
A key differentiating factor is the incorporation of a programmable, Hall-effect IC, which can be used to change the output characteristic of the sensor according to a number of parameters, namely: slant, offset, upper limit and lower limit.
Linearity tolerance is 2% nominal.
The sensor has temperature compensation built-in and the temperature coefficient range is -25 to +85C.
Overall dimensions are 16 x 23 x 32.4mm.
Durability is assured by Murata to 10 million rotational cycle operations.
The SV21 is ideal for use in a wide range of industrial and consumer applications, including feedback sensor in industrial control units, position sensor in measuring instruments, position sensor for high quality, high performance joysticks, and other high-reliability, long-life position sensing applications.
The device is supplied with a plug in connector, for easy assembly with no soldering required.
Murata's keenly priced noncontact rotary position sensors are already in volume production in Japan on standard lead times.
The SV21, along with the entire Murata product portfolio, is fully RoHS compliant.
