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).

Idem Safety Switches is one of the leading design companies for Switches.

Idem has introduced the Guardian Line range of Safety ‘Grab Wire’ Rope switches -the world’s most comprehensive range of Grab Wire Safety switches covering all applications and industry sectors.

One of the areas which makes the Guardian Line new and innovative is in the area of rope connectivity. Traditional ‘turnbuckle’ style rope fasteners and adjusters are prone to rope slippage and require frequent re-tensioning leading to production loss caused by machine down time.

Idem has overcome this common problem by providing a ‘no nuts or bolts’ rope connection system with a ‘Quick Link’ clasp at one end of the rope and a patented Tensioner /Gripper at the other.

The Tensioner / Gripper is located at the switch (rather than elsewhere along the rope length) so that the switch tension window can be viewed.

Final setting and locking can be achieved in a matter of seconds without any need for frequent re-tensioning.
