Product Description:
Developed by the industrial market giant Pacific Scientific, the PMB31B-20101-01 represents a precision component in PMB Brushless Servomotors series for industrial automation. An inductive sensing method detects metal targets without contact thus to extend operational lifespan. An NPN output type enables low side switching that aligns with standard control architectures. Along with normally open configuration, the drive holds the circuit open until activation and can minimize standby current draw.
A 12–24 V DC operating voltage supports wide-range power supplies which simplifies integration. Motor’s current consumption rating of ≤10 mA limits power usage for reducing a thermal buildup. While its ≤100 mA load current capacity handles moderate switching loads which accommodates typical actuator inputs. The 1 kHz response frequency guarantees rapid detection cycles which boost throughput. The nickel-plated brass housing offers robust corrosion resistance and preserves sensor integrity. An IP67 protection rating guards against dust and water which maintains reliability in critical industrial settings. An ambient temperature of -25°C to +70°C holds extreme conditions to retain motor’s consistent performance.
This variant comes with a 2 m cable connection and provides flexible routing options which ease installation in complex systems. A flush mounting design enables the sensing face to sit level with surrounding surfaces to prevent accidental damage. A proximity sensor format senses objects without wear which extends maintenance intervals and 2 mm sensing range achieves precise target detection, guaranteeing accurate positioning. A safe sensing range of 40.5 mm prohibits unintended activations which maintain detection reliability. Also, a switching hysteresis of 10–15 % stabilizes output transitions for reducing a signal chatter.
Frequently Asked Questions about PMB31B-20101-01:
Q: Why does the PMB31B-20101-01 utilize NPN output?
A: An NPN output design allows the module to switch its load to ground, ensuring compatibility with standard low-side switching circuits and simplifying interface with PLC inputs.
Q: How does a normally open output mode benefit the PMB31B-20101-01?
A: A normally open configuration keeps the circuit off until target detection occurs, which minimizes standby current draw and reduces unnecessary power consumption.
Q: What voltage range does the PMB31B-20101-01 support?
A: The unit’s 12–24 V DC operating voltage accommodates common industrial power rails, enabling seamless integration across diverse control systems.
Q: Why is low current consumption important for PMB31B-20101-01?
A: By limiting current consumption to ≤ 10 mA, the servomotor decreases thermal loading and conserves energy, which improves overall system efficiency and longevity.
Q: How does the load current rating affect PMB31B-20101-01’s performance?
A: With a ≤ 100 mA load current threshold, the drive ensures safe handling of actuator or indicator inputs, preventing overload situations in connected circuits.
