26.5VDC Nominal Electromagnetic Induction Coil Operating Voltage, 2 Form C (DPDT) Double-Pole Double-Throw Contact Array, Heavy-Duty Hermetically Sealed Miniature TO-5 Metal Can Envelope Profile, High Reliability 842 Commercial Communications Relay Series Blueprint, Suffix-204-101 Target 24V/26.5V Precision Coil and Straight Soldering Pin Classification, High-Pressure Crossbar Gold-Clad Silver Alloy Material Contacts, Fast-Acting 4ms Typical Operating Speed Loop, Low-Power 500mW Core Coil Energy Dissipation Matrix, High-Fidelity Auxiliary Logic and Telemetry Route Selection Node, High Stability Secondary Power Loop and Peripheral Actuator Driver Switch | High-performance industrial and military-grade high-reliability subminiature electromagnetic signal relay manufactured by Potter & Brumfield (TE Connectivity) under specialized design catalog tracking index 842-204-101. Sharing the identical unibody welded hermetic TO-5 metal can package outline, gold-clad DPDT contact mechanism, and high-fidelity signal preservation benchmarks as its 12V sibling, this upscaled model incorporates a precisely wound high-resistance copper internal coil tuned exclusively to run smoothly on standard 24V to 28V DC instrumentation loops. It translates higher-voltage system triggers instantly into automated circuit routing operations, cleanly isolating core computing modules from hazardous inductive field decay noise and primary power line switching ripples without localized phase distortions or travel lag. Commonly encountered inside aerospace flight telemetry decks, commercial railway operator cabs, power substation automated control panels, and calibrated instrumentation test rigs. | Industry Exact Equivalents: Potter & Brumfield 842-204-101, TE Connectivity 842-204-101, P&B 842-204-101 | Industry Functional Cross-References: Teledyne 722-26, Intersil TO-5 26.5V Relays, Genicom 3SBC Series 28V, Hi-G 26V Miniature Relays, Relays TO5-26VDC
