They are designed to respond to alternating Electronic window lift, anti-pinch power window systems North and South poles. The SS360NT is turned on by a North Vehicle convertible roof position pole while the SS360ST, SS460S, SS460S-T2, and SS460S-LP Medical are turned on by a South pole. These sensor ICs offer reliable Medical equipment using electric motors switching points with a high magnetic sensitivity of 30 G typical (55 G maximum). They do not use chopper stabilization on PORTFOLIO the Hall element, providing a clean output signal and a faster The SS360NT, SS360ST, SS360ST-10K, SS460S, SS460S-T2, latch response time when compared to competitive high SS460S-LP are part of Honeywells family of Latching Digital sensitivity Hall-effect latching sensor ICs which do use chopper Hall-effect Sensor ICs, including: stabilization. These products offer reverse polarity protection, SS360PT, SS460P, SS460P-T2 deliver a stable output over a -40 C to 150 C -40 F to 302 F SS361RT, SS461R temperature range, and can accept any dc supply voltage from SS361CT, SS461C 3 Vdc to 24 Vdc. For brushless dc motor manufacturers who SS461A, SS466A need latching sensors with reliable, consistent performance for more efficient and smaller designs, Honeywells High Sensitivity Hall-Effect Latching Digital Sensor ICs respond to low magnetic fields and offer consistent repeatability while delivering faster response times to a change in magnetic field for better motor efficiency. These products are available in four package styles: SS360NT, SS360ST, SS360ST-10K: SOT-23 surface-mount package, pocket tape and reel SS460S: Flat TO-92-style 14,5 mm 0.57 in straight standard leads, bulk package SS460S-T2: Flat TO-92-style 14,5 mm 0.57 in formed leads, ammopack tape-in-box SS460S-LP: Flat TO-92-style with straight, long leads, pocket tape and reel Sensing and Productivity SolutionsHigh Sensitivity Latching Digital Hall-effect Sensor ICs: SS360NT, SS360ST, SS360ST-10K, SS460S, SS460S-T2, SS460S-LP Table 1.
