Designed expressly for high density PC Board mounting, its small size and low coil power dissipation make the TO-5 relay one of the most versatile ultraminiature relays available. UPPER STATIONARY CONTACT UNI-FRAME ARMATURE LOWER STATIONARY CONTACT MOVING CONTACT ENVIRONMENTAL AND PHYSICAL SPECIFICATIONS Temperature (Ambient) -65°C to +125°C Vibration 30 g’s to 3000 Hz (Note 1) Shock 75 g’s for 6 msec. (Note 1) half-sine Acceleration 50 g’s (Note 1) Enclosure All welded, hermetically sealed Weight 0.159 oz (4.50 gms.) max. The following unique construction features and manufacturing techniques provide excellent resistance to environmental extremes and overall high reliability. • • • • • All welded construction. Unique uni-frame design providing high magnetic efficiency and mechanical rigidity. High force/mass ratios for resistance to shock and vibration. Advanced cleaning techniques provide maximum assurance of internal cleanliness. Precious metal alloy contact material with gold plating assures excellent high current and dry circuit switching capabilities. The 432D and 432DD Series utilizes internal discrete silicon diodes for coil suppression and polarity reversal protection. The hybrid 432T features an internal silicon suppression diode and transistor driver. This hybrid package reduces PC board floor space by reducing the number of external components needed to drive the relay. By virtue of its inherently low intercontact capacitance and contact circuit losses, the TO-5 relay has shown its worth as an RF switch for frequencies well into the UHF spectrum (see Figure 1). In addition, the sensitive 432 Series relay features exceptionally high coil resistance thus providing for extremely low operating power (200 milliwatts typical at room temperature). The advantages of reduced heat dissipation and power supply demands are obvious. 50 SERIES 432 GENERAL ELECTRICAL SPECIFICATIONS (-65°C to +125°C unless otherwise noted) (Notes 2 & 8) Contact Arrangement Rated Duty Contact Resistance Contact Load Ratings (DC) (See Fig. 2 for other DC resistive voltage/current ratings) Contact Load Ratings (AC) 2 Form C (DPDT) Continuous 0.1 ohms max. before life; 0.2 ohms max. after life at 1A/28VDC, (measured 1/8” from header) Resistive: 1 Amp/28VDC Inductive: 200 mA/28VDC (320 mH) Lamp: 100 mA/28VDC Low Level: 10 to 50 µA/10 to 50 mV Resistive: 250 mA/115VAC, 60 and 400Hz (Case not grounded) 100 mA/115VAC, 60 and 400Hz (Case grounded) 10,000,000 cycles (typical) at low level 01,000,000 cycles (typical) at 0.5A/28VDC resistive 00,100,000 cycles min. at all other loads specified above 2A/28VDC Resistive (100 cycles min.)
