|  Series 305 Magnetic Sensors
The magnetic sensors contain a reed switch and are sensitive to changes to the magnetic effects generated by permanent magnets.When the force of the magnetic attraction overcomes the elastic resistance of the blades contained in the reed switch,
the contact changes state.
The contacts are hermetically enclosed in a glass bulb which contains an inert gas. This provides protection from dirt, oxidation and corrosion. The contact surfaces are plated with a precious
metal which allow them to switch low current levels or higher inductive loads.
These magnetic sensors require no power to operate and are ideal for switch closure input applications. Long life and the environmentally sealed aspect of these sensors allow the Model 305 to satisfy numerous unique industrial applications.
The magnetic sensors are supplied as standard with NO contacts but NC or a NO & NC output models can be supplied on special request.
- DPDT Relay Output
- Plug-In On-Delay/Off-Delay/Dual-Delay Timing Options

|  Miniature Scanners
The 7022A, 7064A and 7065A are designed for through-beam or diffuse applications. These sensors must be used with the 7218A or 7219A, which provide modulation, amplification, and control. The 7022A is a diffuse type with an infrared source. The 7064A and 7065A are through-beam and diffuse types incorporating a visible LED and bendable fiber optic sensing tip.
- Miniature Cylindrical Sensors
- Amplifier Dependent
- Through-Beam or Diffuse
- Stainless Construction

|  Ultrasonic Through-Beam Scanner Model 7581A
The 7581A Ultrasonic is designed for through-beam applications. Because sound rather than light is the source, positive detection of any opaque or transparent object is possible. Incorporating a sensing distance of 12 inches, this beam present/beam absent operate switch functions reliably between 12 to 24VDC.
- Ultrasonic sensor with built-in amplifier
- Uses micro ultrasonic elements
- Compact size— .98" × 1.4" × .52"
- 7851 can easily detect food wrapping cling film, plastic containers, glass etc.
- 20 inch sensing range
- NPN or PNP output
