MTE Turck introduces the Banner Q45UR range of remote ultrasonic proximity sensors with exceptional sensing repeatability. The remote unit allows access to small areas and the rugged design permits use in the most demanding environments (see Plate 1).

The Q45UR units have a range from 50 to 150mm, repeatability to 0.1 per cent of the sensing distance set point and a 0.01mm resolution. Available as a kit of controller module and sensor module or as separate units, they accept 12 to 24v dc, or in the case of analogue units, 15 to 24v dc. The controller is rated IP67 and the sensor IP65, allowing installation in most situations.

There are bipolar outputs, one sinking (NPN) and one sourcing (PNP), switchable (normally open/normally closed), with a selectable response time. They will operate over a wide temperature range of -25úC to +70úC and all models include temperature compensation.

The Q45UR controller features a single push button for programming the sensing distance set point and the outer limits of the sensing window are set by means of four DIP switches under a cover on the controller.

Available with an integral 2m or 9m cable or with mini or Euro style quick disconnect fittings, they are ideal for gauging and similar inspection applications. The sensing window can be selected between 1 and 4mm and the set point can be centred in the window.

A microprocessor controlled TEACH button can be used to set the window limits and there is an input for remote TEACH mode window limit programming. Digital filtering provides immunity to random electrical and acoustic noise and there is a comprehensive LED indicator system.

MTE Turck prides itself in having the widest range of sensors from a single source and the introduction of the Banner Q45UR range will further justify the claim. Ultrasonic sensors have an important role to play in sensing clear glass, plastic, transparent films and liquid surfaces - objects that photoelectric sensors cannot see. The Q45UR remote range will considerably extend the number of applications where these versatile units can be installed.
