Enm Quartz DC Analog Hour Meter T41E45 10-80V

The ENM T41E45 is a compact quartz DC hour meter designed to record accumulated operating time in 10–80 VDC electrical systems. Its 6-digit mechanical counter displays hours and tenths without a reset function, making it suitable where a permanent operating-time record is required.

The T41 series uses a quartz-crystal time base for long-term timekeeping. Accumulated hours are retained mechanically, so no battery back-up is required. The DC input is polarity insensitive, and the sealed high-impact plastic housing is intended for durable panel installation.
