A new range of photoelectric switches offers system designers a raft of advantages when it comes to space, installation and cost.
By delivering a focused range of features and capabilities, the new MH15 range of photoelectric switches from Sick (UK) will offer system designers a raft of advantages when it comes to space, installation and cost.
Both compact and inexpensive, their diminutive size belies the fact that the complete range of sensors will provide many industrial applications with a full range of sensing capabilities.
Measuring just 30mm in length, the sensors, with their tough ABS casings, can be flush mounted in extremely small spaces.
Not only does this address the issue of restrictive "real estate" but it also makes them less of a target for accidental damage.
Designed to be fixed into position with M18 locknuts, a full range of mounting accessories is also available and an optional 90-degree deflection can be provided for "round-the-corner" sensing.
The range offers three standard modes of operation: through beam, polarised reflex and diffuse.
Working envelopes are 4m, 2.5m and 100/350mm, respectively.
Through beam is where the sensor is paired with a receiver and relies on an object breaking the beam; polarised reflex, where the sensor and receiver are in the same housing, detects objects coming between the unit and a reflector; and finally diffuse, where a sender and receiver are used to detect the object without the use of a reflector.
Connection is be via a cable or M12 connector and PNP and NPN switching outputs can be supplied.
Typical applications for this highly effective range of sensors are various and include: storage and conveying, packaging, electronics handling and timber processing.
