* The 906B and 907B sensors are used where directional sensing is required. 906 Series Sensor and Pulser Disc 907 Series Sensor and Pulser Disc 907 Series Sensor and Pulser Wrap Optional EZ100 Bracket for use with 907 Series Sensors Product Information Hall Effect Sensors Models 906 and 907 Explosionproof Quadrature Models 906B and 907B Explosionproof • Large gap non-contact sensing • NPN Open collector output • Signal transmission up to 1,500 feet • Compatible with PLC digital I/Os • Easy to install - no maintenance • Rugged and reliable • 907 Series UL and CSA approved to applicable standards • 5- Year Limited Warranty on speed switches, sensors & ratemeters* * Contact factory for more information Description Electro-Sensors’ Model 906/906B* and 907/907B* Hall Effect sensors are designed for use with pulse generators that provide magnetic targets, such as Electro-Sensors’ Pulser Discs and Split Collar Pulser Wraps. 906 series sensors have a 3/4" threaded aluminum body, are supplied with a mounting bracket and jam nuts, and are recommended for use with Pulser Discs and Split Collar Pulser Wraps. 907 series explosionproof sensors are mounted in a rugged cast aluminum enclosure, which is CSA approved and UL rated for Class I, Group D; Class II, Groups E, F, and G, and Class III environments. 907 series sensors are also supplied with a mounting bracket and are recommended for use with Pulser Discs and Split Collar Pulser Wraps. 906 and 907 sensors come with 10 feet of 3-wire shielded cable as standard, and 906B and 907B sensors come with 10 feet of 4-wire shielded cable as standard. Both the 906 and 907 series of sensors can be mounted up to 1,500 feet from the control unit (i.e. speed switch or tachometer). 906 and 907 series sensors are powered by 6-24 Vdc, and provide an NPN open collector output. Hall Effect sensors switch high and low in the presence of alternating magnetic fields, and generate a square wave (digital) signal with a 50/50 duty cycle when used with Electro-Sensors’ pulse generators, which have evenly spaced magnets of alternating polarity. 906 and 907 series sensors allow for a large gap distance of 3/8" ± 1/8" between the sensing surface and the pulse generator’s target magnets. The signal produced by the 906 and 907 series sensors is compatible with all Electro-Sensors’ products, most PLC digital I/O cards, and with other products requiring an NPN type digital pulse input signal. Electro-Sensors’ products bring efficiency and safety to your operations by preventing machine damage, product waste, and costly downtime.
