Introduction
Electro-Sensors, Inc. has announced the release of the Series 18 shaft rotation speed sensors. These sensors are designed to detect passing magnets from a shaft-mounted pulser disc or wrap, outputting a voltage pulse frequency proportional to the shaft's rotational speed. They are capable of operating at speeds down to zero.

Specifications and Options
The Series 18 sensors offer a variety of options to suit different applications. Users can choose between Hall-effect or magneto-resistive sensing, single or quadrature signaling, and NPN (current sinking) or PNP (current sourcing) transistor outputs. The sensors are available in four stainless steel M18x1 housing options: basic corded, M12 eurofast connector, 1/2" rigid, and 1/2" flexible liquid-tight conduit port. These output signaling and termination options are compatible with PLC inputs, tachometers, and various frequency meters.

Design and Durability
All models come standard with a mounting bracket and two stainless steel hex jam nuts. They are filled and sealed to prevent the entrance of liquids and dust, ensuring durability and reliability.
