Low cost photoelectric sensors
The lens material is PMMA plastic making the sensors suitable for use in the food and pharmaceutical industries.
A diagnostic or 'excess' function can be selected with some sensor types which monitors the visible red light detected. This provides a switched output if the light level falls below a safe threshold thus alerting users to dirt build-up or any misalignment occuring while in service. It also simplifies adjustment and set-up during installation
The new Contrinex 'Series 5050' photoelectric sensors have wide supply ranges with DC types 10-36VDC and AC/DC models 20-250VAC/20-300VDC. All are protected from short-circuit, voltage reversal and supply transient spikes to ensure long and reliable operation in harsh environments.
The high specification and highly competitive price makes these Swiss-quality sensors an extremely effective solution for many types of automation applications
