Self-contained sensor and speed switch for detecting shaft slowdown, SPDT relay output, housed in an explosion proof cast aluminum or a corrosion-resistant PVC enclosure.

What is a Shaft Speed Switch and where is it used? A Shaft Speed Switch is a device that monitors rotating shafts that are critical to the proper operation of many types of machinery.

The M100T and M5000T are compact, self-contained shaft rotation monitoring speed switches ideal for detecting unwanted slowdown or stoppage of process equipment.

It is used in slow speed applications and allows accurate under-speed detection within the 1/100-10 rpm range. The SS110 is an efficient way to continuously track proper machine rpm, and provide a relay …

The DR1000 speed switch is ideal for detecting unwanted slowdown or stoppage of process equipment and is commonly applied to drive trains, power driven components, crushers, exhaust fans, screw …

Self-contained, presettable sensor and switch with one or two adjustable SPDT or DPDT setpoint relays to detect over-speed or under-speed. Built-in start delay. Housed in a cast aluminum explosion proof …

Electro-Sensors' Speed Switches are used on Motors to monitor critical speed and guard against slowdown or stoppage that can result in costly process downtime, machine damage, and material …

The Electro-Sensors FB420 2.0 speed sensor provides a 4-20 mA signal directly proportional to the rotational speed of a monitored shaft and has a 4 digit LCD display capable of displaying from 0.000 …

The LRB1000 (single relay, 1 setpoint) and LRB2000 (double relay, 2 setpoints) shaft speed switches are an efficient way to continuously monitor machine rpm and provide relay protection upon detection …

A Speed Switch is used to alarm an operator of any undesirable or critical speed condition of the monitored shaft such as rotating too fast, too slowly, or a combination of these.
