Durable and can withstand stronger vibration, moisture and solvent.
The thermocouple / thermal switch output can be as one of the control signals and trigger other circuit functions.
The low temperature coefficient improves heat conduction and heat convection
Support water resistant and outdoor application requirements, up to IP65
Support brake resistor with thermocouple or thermal switch built-in requirement.
Support dual-resistance values
Support precision Tolerance : +/-0.1% +/-0.5% +/-1% +/-5% +/-10%
Support high pulse current requirement
Support braking resistor with protective enclosure, cooling system and thermal switch
Support miniature size and low profile requirements
For low ohmic values, please state the resistance, working voltage, duty cycle and loading time or number of pulses per sec/min. Different voltages can cause different loading currents.

Braking Resistor Electrical Connection Options:
i) Electrical Lead Wires – support customization like length, type, and colour. The standard lead length is 100mm.
ii) Electrical Lead Wires with different connection terminals
iii) Busbar Terminals – for high pulse current applications
