The 1101 sensor has a non-threaded stainless steel body, is supplied with a mounting bracket, collar and set screw, and is recommended for use with 60-Pole Pair Magnet Wheels or NEMA C Flange Ring Kits. The 931XP Hall Effect Sensor is mounted in a rugged cast aluminum enclosure, which is CSA approved and UL rated for Class I, Groups C and D; Class II, Groups E, F, and G, and Class III environments. The 931XP is also supplied with a mounting bracket and is compatible with Pulser Discs and Split-Collar Pulser Wraps. 1101 and 931XP sensors come with 10 feet of 3-wire shielded cable as standard, and can be mounted up to 1500 feet from the control unit (i.e. speed switch or tachometer). 1101 and 931XP 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. The gap distance between the sensing surface and the pulse generator is dependent on the strength of the target magnets (see the Sensor Compatibility Table on the following page). The signal produced by the 1101 and 931XP sensors is compatible with all Electro-Sensors’ products, most PLC digital I/O cards, and 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.
