Magnetic Proximity Switches

Protocontrol make Magnetic Proximity Switches are designed for speed sensing application and position and direction sensing. Special hall effect switches are ideal for use in automobile speed sensing applications.

Types of Magnetic Proximity Switches
  • Magnetic Proximity Switch Reed Type, With Actuating Magnet
  • Magnetic Proximity Switch- Hall effect type : Solid state output

Types of Magnetic Proximity Switches

Magnetic Proximity Switch Reed Type, With Actuating Magnet

These switches require a magnet for operation. The magnet is supplied with the switch. The reed element which is sealed in the switch operates when the magnet passes nearby.

Salient Features

  1. Non contact operation
  2. Potential free contacts suitable for 24 VDC / 240 VAC.
  3. High operating distance up to 25 mm.
  4. Totally enclosed - Robust - cast Al / Plastic enclosure for switch as well as magnet. IP 67.
  5. A Special stay-put type of switch is developed which can be used to sense direction.
  6. Operating Temp up to 0-120° C

Specification

  1. LOAD CURRENT : 1 Amp
  2. OPERATING VOLTAGE : 250 V Ac or Dc Max
  3. POWER : 80 VA max.
  4. HYSTERESIS : 25 %
  5. ENCLOSURE : Totally enclosed ,IP 67
  6. SWITCHING TIME ON : O.3 ms - 1.5.ms
  7. SWITCHING TIME OFF : 0.5 ms Max
  8. MECHANICAL LIFE : 1 x 106 TO 109 Operations depending on type of load
Sensing distance depends on the power of magnet. By increasing magnet power sensing distance will increase.

Magnetic Pick-Ups

Magnetic Pick-Ups

Magnetic pick up consists of permanent magnet, a pole piece and a sensing coil and electronic circuit. An object of iron, steel or other magnetic material passing closely by its pole face causes distortion of its magnetic flux field passing through sensing coil and pole piece, which in turn generate a signal voltage

Application : Magnetic pick ups are most widely used to sense teeth of a gear, timing belt wheel even bolt head, key-ways.
