Honeywell introduces its SS361RT and SS461R Bipolar Latch, Hall-Effect Magnetic Position Sensors, giving customers the opportunity to help reduce manufacturing costs.

The SS361RT and SS461R sensors’ enhanced sensitivity enables the use of less expensive magnets in some applications. The SS361RT sensor’s very small footprint takes up less space on the printed circuit board, typically allowing for a reduction in costs. Additionally, the SS361RT sensor is supplied on tape and reel, allowing for automated, highvolume, lower-cost pick-and-place assembly.

Honeywell designed the SS361RT and SS461R sensors for potential use in industrial applications (e.g., speed and RPM sensing, tachometer, flow-rate sensing, valve/damper position, brushless dc motors, variable speed drives, motor and fan control, and robotics control), medical applications (motor assemblies, medication dispense control), and transportation motion control applications (e.g., RPM sensing, tachometer, motor and fan control, electric window lifts, convertible roof positioning, and transmission positioning).

Honeywell’s SS361RT and SS461R sensors feature a 3 V supply voltage capability for low-voltage applications. The sensors are available in two package styles, providing application flexibility. The SS361RT’s miniature SOT-23 surface mount package utilizes a tape and reel format; the SS461R’s flat TO-92 style is available in bulk (1,000 units per bag).

New Sensor Features Extended Operating Ranges, Supply Voltages
and Output Configurations to Simplify Control System Compatibility

Honeywell introduces 17 new RPN Series Hall-Effect Rotary Position Sensors that simplify customer use by providing the inputs, outputs and voltage ranges needed for nearly any control system.

Eight operating ranges up to 360° give customers greater control system accuracy by allowing them to select a range more closely suited to their application. Five supply voltage outputs (5 Vdc to 30 Vdc) and eight output configurations (mA or Vdc) improve compatibility with a variety of control systems. Linearity as low as ±0.35° provides customers with increased measurement precision. This precision can be essential depending on the application. Two connector choices (AMP Superseal, Deutsch) satisfy customer connection requirements. The RPN Series’ products also share the same footprint, eliminating special recalibrations and simplifying use.

The RPN Series sensors use solid state Hall-effect technology, providing non-contact operation, enhancing service life and reducing wear-out mechanisms. This Series uses a magnetically based, Hall-effect integrated circuit (IC) to sense rotary movement of the actuator shaft over an operating range. The IC, together with conditioning and protection circuitry and two permanent magnets, is sealed in a rugged package of IP67 or greater for durability in harsh environments. A dual output version is available for redundancy and backup.

This product introduction extends a robust portfolio of position sensors that are found in thousands of vehicles and equipment worldwide. Potential applications include position and movement detection of pedals, throttle, gear shift, levers, linkages suspension and hitches in trucks; off-road vehicles; industrial and construction vehicles and equipment; agricultural vehicles and equipment; and cranes.

Small, Tough Switch for Hydraulic Brake Systems
in Harsh Environments

Honeywell introduces the Series 1000 pressure switch for potential hydraulic brake pressure applications. Honeywell’s Series 1000 switch excels in brake systems used in many harsh environments such as extreme weather conditions or particle-filled areas due to its IP65 sealing and high burst rating. With its high resistance to shock and vibration, this pressure switch is designed to withstand pressure spikes in critical systems.

Honeywell Sensing and Control has utilized our engineering expertise to reduce part count on this product by approximately 75%. With fewer parts, the switch’s cost and complexity are optimized. The new design may contribute to lowering installation time by minimizing the time required for adjustments and potentially the need for field maintenance. The result is reduced field failures, even in the most demanding environments. Custom versions of this product have been in operation for over 2 years in 20,000 ATVs with no known field failures reported.

With its small size and superior sealing, the Series 1000 pressure switch may be used to actuate brake lights in brake systems for small vehicles used in many harsh environments.  Typical vehicles include ATVs, snow, and sport vehicles as well as smaller motorcycles and scooters. The switch may also be used in applications where high operating pressure and low set point are required. Other potential applications may include hydraulic brake systems in small vehicles, compact agriculture tractors, utility vehicles (UTVs), trucks, lift trucks, and other small self-propelled vehicles.

Patent-Pending Design Allows for True Plug-and-Play Installation

Honeywell introduced an adapter for limit switches with 20mm thread conduit openings. When purchased as a pre-installed accessory on a Honeywell MICRO SWITCH limit switch, this patent-pending adapter is ready to mount and plug into a Deutsch DT4 mating connector.

Typical installation time for limit switches includes as much as three minutes to wire a standard-type switch. The plug-and-play adapter may realize cost savings in reducing installation time, minimizing down time for switch replacement, or by eliminating additional parts normally associated with the assembly of a pigtail connector.

The accessory also is available as an adapter kit containing individual parts ready for assembly or as an adapter assembly pre-wired with four lead wires. Both options may provide cost savings over standard installation. Potential applications include aerial/scissor lifts and cable-to-cable applications in off-road, agricultural and construction equipment.
