CAMLogic Inductive Speed Monitor SMD20P Series

Introduction – CAMLogic Inductive Speed Monitor SMD20P Series

The CAMLogic Inductive Speed Monitor SMD20P Series is a non-contact device designed to monitor the rotational speed of any transmission shaft ranging from 10 to 2000 RPM (approximately 30 to 6000 pulses per minute). This compact and reliable sensor automatically triggers a relay output when the measured speed deviates from the configured setpoint, ensuring safe and precise speed control in industrial environments.

Built with a robust die-cast aluminium housing and protected to IP65, the SMD20P provides dependable operation even under demanding plant conditions. The inductive sensing principle eliminates the need for direct mechanical coupling, minimizing wear and maintenance while improving operational safety and accuracy.

Designed in compliance with ATEX standards, the SMD20P is certified for Zone 21 environments containing potentially explosive dust or powder. Its easy installation, adjustable setpoint via rotary selectors, and visual LED indication make it a versatile and user-friendly solution for process monitoring and machinery protection.

The SMD20P Series represents the reliability and quality associated with CAMLogic Italy, available through Dubai Sensor for customers across the UAE and the broader MENA industrial market seeking robust, explosion-safe motion control solutions.

CAMLogic Inductive Speed Monitor SMD20P Series

Q1. What is the operating principle of the CAMLogic SMD20P?
The SMD20P is an inductive, non-contact speed monitor that senses the rotation of a ferromagnetic actuator attached to a shaft. It detects rotational frequency and activates or deactivates a relay when the speed falls below or exceeds the configured setpoint.

Q2. What speed range does the SMD20P cover?
The device monitors speeds from 10 to 2000 RPM, equivalent to 30 to 6000 pulses per minute.

Q3. How is the speed setpoint adjusted?
Configuration is done via three internal rotary selectors corresponding to thousands, hundreds, and tens of RPM. This allows precise, user-friendly setpoint selection.

Q4. What are the available power supply options?
The SMD20P operates with 115/230 VAC, 24/48 VAC, or 24 VDC ±15%, consuming just 1.6 W of power.

Q5. What is the maximum switching capacity of the relay output?
The integrated SPDT relay supports up to 5 A at 250 VAC, suitable for control circuits and alarm systems.

Q6. Can the sensor be used in explosive or dusty environments?
Yes. The SMD20P is ATEX-certified (Ex II 2D Ex tD A21 IP65 T87°C) and suitable for Zone 21 installations with combustible dusts or powders.

Q7. What is the environmental protection rating?
The device has an IP65 rating, meaning it is dust-tight and resistant to water jets, suitable for both indoor and outdoor installations.

Q8. Does the SMD20P require regular maintenance?
No. The sensor is maintenance-free during normal operation. Only damaged or worn parts should be replaced as needed.

Q9. How should the sensor be installed?
It can be mounted in any position (radial or axial alignment) using the aluminium bracket. The sensing head must be positioned ≤10 mm from the actuator surface for reliable detection.

Q10. What safety precautions are necessary for installation?
Both earthing terminals must be connected to ground. Installation in ATEX areas must comply with IEC 60079-14 and use certified cable glands.

Q11. What warranty does CAMLogic provide?
