Product Description:

The PSP-1 controller switch is a product of Danaher and it works by detecting magnetic fields. The company showcases high-grade designs that are well-suited for various mechanical platforms.

The PSP-1 controller switch uses a Hall effect where a magnetic field activates the switch which helps in enabling accurate detection of proximity without direct contact. It employs a PNP output configuration by ensuring link with sourcing input circuits commonly used in industrial automation. The contact arrangement is normally open which means the output remains inactive until a magnetic field is present near the sensor. It is supplied with an integrated cable assembly that measures 3 meters in length by offering ample distance for flexible installations. The weight of the entire assembly stands at 0.07 kilograms and is easy to handle. It bears the CE and UL marking which aids in affirming its certification with European safety and operational standards. The cable comprises 26 AWG wires which are suitable for signal transmission over the provided length with minimal voltage drop. The operational voltage range supported is typically 10 to 30 volts DC powering most low-voltage industrial automation control systems.

The PSP-1 controller switch electrical parameters include a current consumption generally less than 10 milliamps when unloaded and an output current is found near 100 milliamps by fitting for interfacing with a variety of control devices such as PLCs and relays. The housing is often constructed from ABS material and is capable of tolerating standard environmental pressure. The operational temperature range extends from -25 to 70 degrees Celsius. The protection category is rated at IP67 by allowing safe function in dusty or wet conditions.

Frequently Asked Questions about PSP-1:

Q: What is the sensing mechanism in PSP-1 Hall effect switch?

A: The PSP-1 uses a Hall effect sensor that detects magnetic fields, converting the magnetic flux into an electrical signal for precise non-contact switching.

Q: Why does PSP-1 utilize a PNP normally open output configuration?

A: The PNP N.O. output ensures sourcing current for positive logic circuits, making it compatible with most industrial PLCs and control relays.

Q: Which voltage range supports optimal operation of the PSP-1?

A: The PSP-1 operates reliably within a 10-30V DC range, ensuring compatibility with standard low-voltage industrial power supplies.

Q: What housing material safeguards the PSP-1 switch from mechanical stress?

A: The PSP-1 features a durable ABS housing that provides robust protection against impact, vibration, and environmental contaminants.

Q: What ingress protection rating does the PSP-1 typically possess?

A: The PSP-1 usually carries an IP67 rating, making it dust-tight and capable of withstanding immersion in water for limited durations.
