SS461A

Product Description

The SS400 Series and SS500 Series are small and versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet, and are designed to respond to alternating North and South poles, or to a South pole only. They are available in bipolar, latching or unipolar magnetics. On-board regulation provides stable operation over a 3.8 Vdc to 30 Vdc supply voltage range. These sensors are capable of continuous 20 mA sinking output and may be cycled as high as 50 mA max.

The 3.8 V capability allows for use in many potential low voltage applications. The digital, open collector sinking-type output is easily interfaced with a wide variety of electronic circuits. To provide reliable products and consistent quality, the SS400 Series products are tested at both 25°C [75°F] and 125°C [257°F]. All catalog listings are qualified for operation up to 150°C [302°F]. For design flexibility, these product are available in the following package styles:

- SS4XX: Straight standard leads, bulk pack

- SS4XX-L: Straight long leads, bulk pack

- SS4XX-T2: Formed leads, ammopack tape-in-box

Performance Specifications (Applies to both SS400 series and 500 Series, unless otherwise noted.)

^{1For supply voltages above 24 Vdc, a capacitor may be needed between the output and supply pins to ensure proper operation.}

NOTICE

These Hall-effect sensor ICs may have an initial output in either the ON or OFF state if powered up with an applied magnetic field in the differential zone (applied magnetic field >Brp and <Bop). Honeywell recommends allowing 10 us after supply voltage has reached 5 V for the output voltage to stabilize.

The magnetic field strength (Gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic characteristics. To test the switch against the specified limits, the switch must be placed in a uniform magnetic field.
Absolute Maximum Specifications

NOTICE

Absolute maximum ratings are the extreme limits the device will momentarily withstand without damage to the device. Electrical and mechanical characteristics are not guaranteed if the rated voltage and/ or currents are exceeded, nor will the device necessarily operate at absolute maximum ratings.Magnetic Specifications
