The latest addition to the range of Remote Sensors from Balluff-Multiswitch is a high power model, designed to transmit input and output signals, in addition to power, across an air-gap (see Plate 6).

An effective and maintenance-free alternative to mechanical connections and slip rings, the new High Power Remote System is intended for installation wherever there is a need to make electrical connections within a moving environment. Typical applications include indexing tables, removable dies and moving work pallets.

Two versions are currently offered: power-only and power-sensor. The power-only model comprises local and remote sensing heads which are capable of delivering one amp at 24VDC across a 46mm air-gap, and is ideal for locations where sensor feedback is not required. These range from the charging of batteries for unmanned vehicles to supplying power for electrical devices on test stations and robot end effectors.

The more sophisticated power-sensor version incorporates amplifiers in PNP or NPN configurations to manage sensor signals, and obviates the need to hard-wire sensors and limit switches on robotic assembly equipment, packaging and injection moulding machinery, machine tools and stamping presses.

For use with virtually any 24VDC switch or sensor, including mechanical, inductive, air pressure, photoelectric, capacitive, magnetic or ultrasonic devices, the system also features a reserve power connection, providing an additional power source for remote auxiliary devices such as solenoid actuators and small motor drives. Bi-directional transmission of up to eight input/output signals is offered.

Installation and set-up of the new remote system is simple: integral "Power On" and "In Zone" LEDs indicate correct transmitter/receiver alignment and provide at-a-glance confirmation of system status.

With transmitting heads sealed to IP67 for use in wash-down environments, the Balluff High Power Remote sensor ensures positive power and sensor signal transmission in most contaminated environments, including those carrying oil and coolant particles, metal chips and dust, and also through glass or plastic barriers.
