　　Industries: Engine and Vehicle, General Industry

　　Description: Sliding the MLS-Sensors along a magnetic scale will produce a sine and a cosine output signal as a function of the position. In order to deliver satisfying results, this will be achieved as long as the air gap between sensor edge and magnetic scale surface does not exceed approximately half of the pole pitch. As the sensor principle is based on the anisotropic magneto resistance effect, the signal amplitudes are nearly independent on the magnetic field strength and therefore air gap variations do not have a strong effect on the accuracy. The sensor detects a magnetic gradient field and is thus almost insensitive to homogenous magnetic stray fields.

　　Features:

　　Sin- / Cos-output signals suitable for signal evaluation by standard-ASIC’s
　　Very high precision
　　Insensitive to air gap fluctuations
　　Highly reliable
　　Low interference field sensitivity

　　典型應(yīng)用: 線性位移和速率測量，用磁極輪做角度測量

　　行業(yè): 發(fā)動機(jī)和機(jī)動車輛, 工業(yè)控制

　　產(chǎn)品描述:

　　MLS傳感器沿著磁尺移動將產(chǎn)生一個正弦和余弦信號。為了得到滿意的結(jié)果，傳感器邊沿與磁尺表面的間隙不能超過半個磁極距。由于傳感器是基于各向異性磁阻效應(yīng)，信號幅度是獨(dú)立于磁場強(qiáng)度的，因此間隙的不同不會影響測量精度。傳感器檢測磁場梯度，所以對均勻雜散磁場幾乎不敏感。

　　特點(diǎn):

　　正弦/余弦輸出適合標(biāo)準(zhǔn)ASIC信號評估

　　高精度

　　對空隙變化不敏感

　　高可靠性

　　對干擾場不敏感
