M3003, M3008 & M3007 Slipswitch
The M300 Slipswitch is an easy-to-use inductive proximity shaft speed monitoring device with an adjustable 0 - 30 second start-up delay, all housed in a 30 mm diameter moulded body. The self-contained unit has a single set point, which signals when the shaft speed has dropped by 20% of normal running speed. It is used for detecting dangerous slow down and underspeed conditions on conveyors, bucket elevators, air locks, mixers, fans, grinders and many other machines.
No connection is necessary between the sensor and the equipment being monitored. The proximity sensor detects a stud or bolt mounted on a shaft, or other suitable target. Ideally, the target should be of ferrous metal, but non-ferrous metal will be detected at a shorter range. Maximum range of ferrous targets is 8 mm (5/16”) and for non-ferrous targets is 5 mm (6/16”), assuming a 20 mm (3/4”) diameter target. Smaller targets may be used but operating distances will be reduced.

Accessories
The Speed Relay is a microprocessor controlled digital speed monitor for use with 2, 3, 4 wire NPN/PNP sensors, 4B’s WDA range of sensors or Contact sensor inputs, with a user programmable electromechanical relay and PhotoMOS Solid State Relay (SSR) outputs. The Speed Relay has a 160x80 pixel LCD display to provide information, and 3 front panel buttons to program settings.
Monitors
The X400 Elite is a microprocessor controlled low cost alarm indicator panel for use with level indicators, hazard controls and limit switch sensors. The X400 accepts signals from different sources in up to 8 zones, and is able to cause alarm and shutdown of the machine when an alarm condition has been detected.
FAQ's
In the product documentation, there is a reference to "load". What is it and how big does it have to be?
Load is the input circuit of the PLC, relay coil or anything else the sensor output if fed into. the load need to limit the current through the M300 sensors to within the specified limit.
When checking the 2 wire M300 with a voltage meter, it is always showing the supply voltage no matter if the shaft is turning or not. Why is the sensor not changing states?
The sensor will not function correctly until a load is connected to it, maximum current through the sensor is provided in the product manual.
How many wires are needed to run the 5 wire version of the M300?
Three are needed to run the sensor, talk to our technical staff or refer to the product manual for more details.
How do you calibrate the M300?
The calibration of this sensors is a very easy procedure for which you will need a magnet, which is supplied with the sensor. Please refer to the operation manual for the detailed instructions.
