Versatile photoelectric switches are easy to integrate

Paul Boughton
IMO's new SQ range of 'bright' photoelectric switches offers users the practicality and flexibility of universal AC or DC operation over the multi-voltage range from 18-240V AC/DC. This feature, together with the SQ's practical relay output, makes it easy to integrate the sensors into machines. It also reduces costs and inventory, as one type of photoelectric sensor can be employed across all machine types.

The new SQ photoelectric sensors are 'bright' units, designed specifically for conveyor and materials handling applications. Available in diffuse, reflective and through-beam versions, with both visible red and infrared emission, the SQ units offer a wide sensing range from 40mm to 20,000mm. Also extending their application scope is the sensor's facility for operation in the temperature range -20 to +60degC. This enables the switches to be used in barrier and door control applications where they may be exposed to harsh outdoor environments.

SQ sensors are equipped with bright top-mounted LEDs to indicate power and output status. Two connection versions are offered: cable or M12 plug. Connection of the sensors via an M12 plug enables rotation through 90 degrees to suit different cable run directions.

In common with all its other sensor products, IMO is supporting the SQ range with its three- year guarantee. This is complemented by CE, and both UL and cUL approvals on all models, offering OEMs the benefit of compliance across most major markets.
