The standard system includes either an M100T or M5000T switch, and a 255 Pulser disc. Electro-Sensors’ speed switches bring efficiency and safety to your operations by

preventing machine damage, product waste and costly downtime.

Miniature Speed Switches contain a sensor and switching electronics in an explosion-proof and waterproof cast aluminium housing. Each switch is supplied with a shaft-end mounted Pulser Disc (or optional Split Collar PulserWrap) which generates an alternating magnetic field that is picked up by the speed switch. The switch decodes this frequency signal to determine shaft speed and compares this to the pre-adjusted set point, easily calibrated via a single-turn potentiometer.

In the event of rotational failure, such as a broken drive, belt slippage, product overloads or clogs, the relay can be used to provide an alarm or equipment shutdown, assuring machine protection and process integrity.
